2010 Prius will not start after sitting for 6 days in snow

It is also good to check where the negative cable attaches to the chassis. Some people have found that loose.

 

in theory yes, but you probably missed the part about radio and lights working fine. the ECU need a good reset after this botched battery change.

 

I didn't miss it. As an industrial electrician, I've seen countless weird things happen with loose connections.

 

And/or try to float some solder into it?

Might be worthwhile to find a kosher crimper tool. Something like this, believe it's the one I've got. Not sure if the max size crimp would be suitable for the ground cable, might be:

FWIW, I found this model a bit of a pain to use. It locks progressively with each squeeze, but the release mechanism is awkward to use. It works though, just not the one I would choose if I was using it a lot.

 

what new part?

 

LOL!

thanks, all the best!

 

Any time the battery is disconnected you are resetting the ECU of the car. What that does is erase all the trouble codes the car has stored in it's memory.

 

Good luck, keep us informed.

 

Ok, that's comforting. I didn't even want to mention the HV battery, because of the cost to replace it. I'm glad it's something else.

[QUOTE="TrvlArrngr,my negative terminal cable is loose - you can spin it around. does not seem to make a difference for the accessories and lights though.

That was one of my first suspicions. It's hard to explain that all the accessories and lights still worked normally, though. Did you turn everything off before attempting to put the car in Ready mode? Possibly the accessories and lights were drawing so much current that there was nothing left to fire up the computers. Anyway, if you are going to put the 12V on a charger and tighten all your connections, hopefully that will solve all your issues.

 

$450 for a china battery and a 2 foot cable and the 10 mins it took them to remove the battery and test it.... that's just sad.

 

4 volts max on a new Ultima battery that was running the headlights? Sounds suspicious. Too bad the code reader neighbor did not have a voltmeter to check it at home. Fingers crossed that another new battery and cable does it.

 

it's called capitalism. I've seen much worse in healthcare and no one objects (I guess due to 3rd party payers).

 

Off topic, but I object every chance I get.

On topic, this is turning into quite a strange story. I sure hope the New Bern dealer gets you all fixed up, @TrvlArrngr. And, if it makes you feel any better, the OEM Toyota 12V battery is an excellent battery.
