Red triangle and exclamation mark after replacing module

agreed, nice guy and will share what he knows, I stopped by his shop recently, impressive operation

Having a module in backwards would not cause heating it would subtract 14.4 volts from the battery voltage and the module pair voltage giving a reading of zero for that module pair along with immediate fault codes and red lights. Removing a module would loose 7.2 volts putting it in backwards would remove another 7.2 volts.
The most likely cause would be a corroded or loose bus bar nut.

To have faith or no faith? That's the question.

 

Congrats on finding it. Keep us posted and let us know if that fixes it. I've got one that's throwing the battery code sometimes but there is only .2V difference between min and max block voltage. Wondering if I've got a bad connection somewhere.

 

corrosion?

 

Are you testing statically or under load?

 

BAD.

Different resistances.

This story adds to the pile: People who try to save money by buying less expensive but crappy solutions come out way behind. For anyone counting, he has now spent ~ $1200 and a lot of time and hassle for 9 months of car use. Instead of paying $2000 for a simple DIY install 9 months ago good for the remaining life of the car.

 

not everyone has or feels its worth investing 2,000 in a 8 year old car (or older) I have two Pri and when the battery packs fail I will try to rebuild them myself with salvage cells and if that fails Ill just sell them as parts..why speand 2 or 3 grand when the car isn't worth 4?

 

If you still have module you have removed I suggest you try re-hydrating them as in my post on re hydration. If they have not been damaged by reverse charging of one cell you may not need to buy any more modules.

I just got a 2004 prius base last week in orando, runs and drives fine ac isn't great but getting 52 MPG over the 100 mile trip home, I was going to take it to Macco in the morning or cheap re spray but thought why spend 4 or 500 on paint that will look like crap in a year or two..Ill do it myself and live with it, its just a car that can de or be wrecked at any time

 

Then take out a loan, even from a credit card. It will be a much smarter move than any other car alternative.

If your credit is so trashed that no type of loan is available -- well, you screwed one lender too many.

 

If the car is a Prius that has otherwise been taken care of, spending $2000 for years and years of battery worry free driving is a no brainer.

If you doubt me, go to the used car lots and see what $2000 will buy you.

Because you are confusing apples and oranges.

$4,000 may be what a used car lot will pay for your car (if that, since the battery is toast.)
You should be asking yourself what it will cost to replace the Prius you have.

Or answer this question: how much would your Prius sell for on a used car lot after a brand new battery had been installed ?
