    A simple battery booster type of box will work well for starting a Prius with a dead battery. The current draw is much less than that for a normal car, so almost any one will do. The types that plug into a 12 V socket won't work, as the power outlets are disconnected until the car powers up. Many people carry a rechargeable unit that also has an air compressor.

    I thought there was a way to dispute a warranty claim with Toyota. I believe you go to one-way binding arbitration. You meet the arbitrator. They make a ruling. If the consumer agrees, Toyota must abide by it. If the consumer dissagrees they can sue if they want to. Why doesn't Ginny try that?

    I was one of those folks who had their Prius turn off at 65 mph on the freeway at night with about 7,000 miles on it. I coasted to the side but was nearly hit 3 times until some kind folks stopped and helped me push the thing uphill to the side of the exit. It would not restart, and the inside and outside lights wouldn't turn off.

    Then the Toyota Regional director was obnoxious to me. First he said I had run out of gas - I was low, but there was gas in it - then the warranty wouldn't OK a rental and I was stuck 60 miles from home at midnight after the car was towed. I called my dealer the next day after going online and finding 60 + people with the same problem. The dealer didn't know anything about these failures and was shocked when he went online. The regional office was intransigent. 2 days later I got a call from the dealer where it was towed to saying that they were flying someone in from NY to replace the computer which had failed. They, the repairing dealer, finally oked a rental car. The regional office was still making like it was "my fault"but the dealer was clear that it couldn't have been my fault since I was just driving on the freeway when it happened. I don't know what has happened to Toyota's customer service, but I, and my kids, have owned Toyotas for years and rarely had a problem, then, if we did the company was great to deal with.

    Things are very different now. Keep the pressure on your dealer and talk to your regional rep. GOogle "inverter failure Prius" on the internet and find others who may have had the same problem. Keep at them steadily and courteously until they do something.

    I hate to say it, but they will more often pull this on a woman than a man. Hang in there, then if they don't eventually make it right contact a lawyer. Also, have a man or several people call about your situation. The squeaky wheel eventually gets grease.

    In your case the dealer was very upfront and cooperative. Just an afterthought in Ginnys case, (don't know what is going on there) to continue, I dropped into Toyota parts and inquired about the where-abouts, part# and cost of the 120A fuse. He was extremely cooperative and friendly, but really could not identify the fuse nor ascertain it's location from the parts diagram. He did however readily volunteer that THIS is the fuse which prevents reverse polarity damage!!! So appparently this is a well known and oft discussed subject at Toyota dealerships. The question begs: What is the function of this 120AMP fuse (fusible link) according to Toyota designers. So...................what happened to Ginnys car?????????

    ANDY....good question....what happened to mine. Finally got the dealership to admit the battery was defective. They also admitted they never tested the inverter. He said he would get the battery covered under warranty. I said will get the fuse link covered also so you can really test the inverter. After 2 days, I hear nothing....call and 3 hrs after I call they send me an email that says they replaced the battery and fuse link and tested the inverter....inverter is burned up. They said the battery was covered by warranty, but I would have to pay for everything else i.e. towing, diagnostics, installation of the fuse link ..minimum $716.77 if I had the car now towed elsewhere....and $4, 637.77 if I want the new inverter put in by them. They have never given me the option to have a used inverter. Can't believe I should have to pay for everything....and certainly not the 716.77 since they did not have my authorization ....only for the warranty parts.....This place is so unreasonable and underhanded....how do I know that they tested the inverter properly....how do I know whether the inverter had a leak or bad cooling pump.....they can not be trusted for anything. They can't even give me an itemized bill........all I ever get is one number thrown at me.

    I still wouldn't trust them.

    Pay the bill and have the car towed to a reputable dealership. Then dispute the charges under warranty with Toyota. Sue the dealership if you have to.

    Quite frankly, I don't see that they've 1. proven the inverter is fried, 2. proven anything was your fault. They have proven that they don't seem to know what they're doing which to me is a red flag to have someone else work on my Prius.

    Did you ask if they have a certified Prius Tech? If they do, have you talked to him?

    This is amazing, I can understand that the work cannot be guaranteed with a used inverter. The crux of the problem is: Is there protection against reverse polarity at both the battery position and the jumper position. ( to protect inverter ) Pat says possibly NO, if that's the case, Toyota has a very bad case against them. This is not just your problem and a uncooperative dealership. This is a serious problem that Toyota has to address nationally. I would take Godivas advice and also elevate to a national TV or radio station. That inverter at $5000 apiece should be totally protected. We can discuss all we want, but there is no national exposure and unfortunately Ginny you are elected.

    Perhaps if a large number of owners emailed Toyota asking how they can prevent Ginny's dilemma from happening to them, they might get some useful feedback.

    My concern is why something so easy to mis-connect can cause so much damage, and only to inverter, nothing else seems to be bothered.

    Why is the owner held responsible? Any service person could have made the error, including the dealer. Just because a person is a certified Toyota tech doesn't make them immune to brain farts.

    SCRUGE: do you really live in Texas? The nick name of the tech here is Scruge? He is evidently the 2nd best in the world for hybrids. That is why I am not going to say there is bad tech work. I am concerned that the service manager is either ignorant or sly like a fox and I have since this incident found out the current owner of the dealership is a son-in-law of the original owner. The original owner was very honest and took very good care of his customers.........not so with this new owner.....heard just the opposite. They go out of their way to charge the customers what ever they can when every they can. They do not want to show warranty work. Seems I am a likely hit for them. If they would restate my case with corporate everything could be handled through warranty, but as it is now, corporate has logged the statement no defects...no warranty period and I heard nothing can change that except the local dealer. (they have a nice racket going each one point to the other) Even though according to the service manager they got the battery paid for under warranty (however could be a misrepresentation )....they could have just put it in to cover their rear ends from only guessing back in May.

    I will try to get the owners email address and then maybe we could start with the folks here emailing him. His name is DH Moss. Will have to find actual email address. Does anyone have an address at Toyota Corporate that we could send inquires to regarding protecting the inverter.

    What I don't know is whither they checked the pump....Did someone say there would be a prius icon lite on the dash. I vaguely remember seeing one of those .....does it flash or does it stay lit? Maybe my inverter went bad first. Would that cause the battery cells to be dead?

    Pat said in a different thread that inverters can fail. Usually because of coolant pump stops running which causes the electronics to overheat. They did say my inverter was burned up......they didn't say just a diode was burnt. Pat says a high voltage leak to ground will not prevent the car from running. When a DTC is logged, the master warning light and hybrid vehicle icon should turn on. I think I have seen a shap of a prius flashing before....is that the icon he referes to??? and does it flash or stay on????

    Another possible failure scenario per Pat in post #20 is that if car had one or two dead battery cells the battery would lack power to start the car. When a jump start voltage was applied the car would start. Once the DC to DC converter started working , it would realized the 12V bus was low (due to bad battery) and increased current output. The shorted battery cells result in excessive current flowing to the battery, which would pop the DC/DC fuse link or the large fuse located at the battery's positive terminal fuseblock.

    I asked the service manager which fuse was bad and he did not know. It is funny as Pat said that only one fuse is bad. I have no assurance they did a full diagnosis on all the fuses or the inverter and coolant pump.

    You should contact the American Arbitration Association at AAA - Arbitration, Mediation and other forms of Alternative Dispute Resolution (ADR).
    They may have experience with this type of problem.
    You can file a brief yourself without requiring a lawyer if the claim is under $10,000.
    If you do file with the AAA it will cost both you and the dealership approximately a few hundred dollars which you will get back if you win the case.

    Hi Ginny,

    Thanks for the update. It would be interesting to know what are the DTC now that the battery and DC/DC fusible link have been replaced. All of the old codes should have been cleared first, so that the tech can see what DTC currently are being logged and what problems still exist.

    If no other fuses popped, this provides evidence that the battery had been properly jumped both by you and the tow truck driver, which is what you asserted all along.

    Regarding a salvage inverter, a Toyota dealer will not install used parts. So you would have to find an independent mechanic willing to learn how to do that procedure.

    Another poster asked where the 120A fuse is located. It lives in the fuse block on top of the positive battery terminal, located under the right-side back of the hatch. This fuse would not protect against an improper jump start if the jump cables are connected directly to the battery. The fuse might protect the battery against an improper jump start if the jump was performed at the front of the car.

    The 100A DC/DC fusible link may or may not protect the inverter against an improper jump start. Based upon other posts, it appears that some owners are lucky while others are not. Hence I conclude that the diodes at the DC/DC converter output must be rated very near 100A current capacity - so it is touch & go whether the fusible link or the diodes pop first.

    Thanks Pat.
    Now that I have email dialogue established with them, I will ask what tests they performed, Which fuse popped, did they test the pump to see if it was working, and what codes came up after all cleared off? This way I will have these responses in writing. Also saves on my cell minutes which have almost been used up for the month just on calls regarding my car.

    PAT....can you tell by the part no. they gave me as to which fuse they replaced. I asked the service manager and he said he didn't know and he never got back to me on it. They say they replaced fuse link PN 82610-47050 $59.82. They did not list any other fuses. And they did not say if they checked any other fuses. No I need to ask any questions regarding the fuse????

    When you say there is evidence I did jump the car properly since only one fuse popped. Which one gives that evidence. The one at the inverter, or the one at the battery?

    If the battery had dead cells, and the jump caused the fuse to pop......would the fact that 2 items were bad then cause the current to back up into the inverter and that is why it got fried......ie all because the cells in the battery were dead to start with.???

    Or could a bad coolant pump fry the inverter which inturn caused the battery and fuse problems to surface..........

    All I know is I did not jump wrong and the tow guy did not jump wrong (it is their tow company of choice...toyota uses them for all their tows so he knows how to jump these hybrids)...............

    ANDY: No I do not have possession of the battery and they say they warrantied it....so doubt I could get it. They have my car too. They are 85 miles from my house, not easy to go check up on them.l

    Hey, when I get this car fixed, I WANT TO SELL IT.................what would be a fair price and does any one want to buy it????. Don't think it is a good car for my snowy, mountainous area or for me as a retired single woman................to sensitive and requires special treatment....and long hours of driving to charge the battery....I am 5 minutes from town.......not to mention it needs to be towed every time it has a problem......It may be good in California for a long distance commuter person which I guess how most of them are used.

    alright... kinda lost track of all that's going on but let's see what info DH can toss out there for consumption.

    $716 for all that but the inverter... consider yourself lucky. :/

    sorry, but if this tech is the second best in the world for hybrids, he's either intentionally trying to screw you by not even testing the inverter prior to telling you that you need a new one OR he doesn't know HOW to test the inverter and really isn't the second best anything.

    none of the codes they found initially would indicate a bad inverter coolant pump. it indicated a burned up dc-dc converter. and by "burned up" it is probably meant the electronics and not a literal overheat.

    post 20 is not a valid scenario. the 12v cannot draw more than the fuses will allow. even a battery with 1 or 2 flaky cells would probably be enough to start the car. DH has seen batteries with pretty low voltage start a prius- one classic he worked on had a battery that tested with his dmm at under 7v and the thing started!

    the fuse link in the big gray plastic box we've been talking about is more expensive than $59.

    oh- one more thing- get the list of NEW codes they've retrieved now that they replaced that fuse link. when they replaced your 12v, the old codes cleared. so the new codes will tell your new story after replacing the fuse link and battery.

    Hi Galaxee,

    See post #14 from the following string:
    http://priuschat.com/forums/care-ma...02-12v-battery-replaced-wrong-polarity-2.html

    In that post, Jenny indicated that the fusible link in the grey/clear box cost her $60.
    Hi Ginny,

    I could not find the part number that you listed in the parts catalog of the Toyota dealer where I buy parts. However, the $60 price that you cited is the same price as Jenny quoted in the post that I mentioned above. On that basis I assume that your tech also changed the same fusible link assembly which is located in the main relay/fuse box near the driver's side fender. This assembly contains multiple fusible links including the 100A DC/DC fusible link that is intended to protect the DC to DC converter.

    Note that Jenny's post #14 also indicated that the DOME and ETCS fuses popped as a result of her installing a battery with incorrect polarity. So if those fuses survived in your car, that would be some evidence that the car was not incorrectly jumped.

    Your msg says that you don't know for sure whether the tech has checked all fuses. I think this is a reasonable concern. I'd like to understand what are the new DTC codes that have been logged before we rule out the inverter coolant pump as a problem.


    It may be worth your while to pay $700 (or a mutually-agreed to amount) so that your car can be released from the dealer's parking lot, and tow it to another dealer for the purpose of:
    • verifying that all fuses are functioning
    • clearing existing DTC codes
    • powering up the car to see what DTC currently exist, and recording them
    This will provide you with a second opinion about whether the inverter needs to be replaced.

    patrick,

    there would have been a code stored prior to the car failure if the inverter coolant pump or an overheat was a problem. now if this code shows up after replacement of the fuses, then sure it needs to be looked into. but the fact that the code was not present upon initial failure pretty much excludes that problem from initial consideration. at least from the diagnostic troubleshooting standpoint.

    there's just a whole lot of speculation going on and not enough evidence to back most of it up. from all sides- even the dealership, who couldn't back up the inverter diagnosis because they didn't *do* it!
