My Prius Battery rebuild experience

So got finally figured it and installed everything right as far as I can tell. Put the battery back in. All the lights are still on and the battery is not charging. No what?

 

Your right it charges when I hit the accelerator. So I how do I clear the lights and code? In the ChrisFix video they cleared themselves when he turned the vehicle back on

 

I disconnected the 12-volt battery for almost twenty minutes. I still have the same warning lights but this time the green/blue "Ready" light also turned on. I took it for a test drive around campus. It is quick and nimble again. Just have to get those lights to clear.

 

I am glad I bought one then. I could not sleep anyway and not getting anywhere with the homework. So let's go play with the Prius in the Parking Lot at three in the morning! So I plugged the scanner and cleared the codes and they would go away for a few seconds. Then I heard some clicking sounds in the back, most likely in the battery, and lights came on again. Tried a different app that cleared the codes and said to disconnect the 12-volt battery for five minutes. So I made it ten minutes just to safe. Reconnected the battery and the warning lights returned. I repeated the process again and just going to leave the battery disconnected all night. As I am typing this I just realized do I also have to unplug the scanner or I just keep it plugged in? Also, the delicate metal bridge thing is in place with the open end pointed towards the liftgate, as the instructions said. It did not get bent either. I have yet to put the metal cover on that goes over the left side of the battery, over the ECU. Could this also be an issue? Here is what the two apps said about the codes.

 

Looks like one of those smaller cables, most likely 7-7, got frayed when putting the plastic covers back. Probably when pushing down the cables to get the covers over them. Is it safe to drive it about five miles to my friend’s place that can repair it?

 

Got the new harness on, tested the Prius, it worked fine. Put the cover back on the battery and all the bolts that hold the battery to the car. Tested it again and it worked fine. I started putting the interior back. I decided to move the car up a little out of the sun. Prius did not start nor ready. Disconnected the 12-volt battery and/or the safety plug a few times for up to twenty minutes. Then had to jump start it. The hybrid battery will not engage and the 12-volt battery does not seem to be working. However, Toyota said that the 12-volt battery was great condition. Yah, so much fun, now what?

 

Yes, I decided to clean this oil goo from gas additive that spilled all over the plastic compartment and every thing underneath. I left it open the whole time. I figured it drain the battery. Jump started it but could not get the Prius to ready. The car system and lights only turn on while it is jump starting. Every thing soon goes dead shortly after the jumper cables are disconnected. The 12-volt drops voltage pretty quickly. It was completely fine before all of this. Maybe I need to check its connections.

I checked the connections and they seem fine. I removed the negative cable and bend it back into shape. I put the lead back on the bolt and screwed it back in. I noticed an amber light on the start button getting brighter as the bolt got tighter. Then the dome lamps slowly started turning on and also started to brighten. I just closed all the doors and locked it. I going to leave it like that for a while. I think I might have fixed the problem. Is the bolt that holds the negative connection into the chassis special or will anyone that fits do?

I guess it is super dead and need to keep it the other vehicle hooked up until the engine hopefully starts up?

 

I found the source of the strange smell after driving around for a while. The corrosion has fused the screw and bolt together. The bottom of the screw has come to lose from whatever holds it down. So when everything just turns when I use a socket wrench. This is the bolt that holds down the main power connector to the battery that is closest to the liftgate. Any ideas how to get the nut off and get the screw out (I probably have to replace both at this point) and where to get the replacements?
