Sometimes a battery will fail internally and short things out -- even to the extent you can't jump it.

Also check the negative terminal and negative connection from the battery to the chassis.

I would also look for voltage at various points around the car.

Will check. Thanks
Tried but without success.
I ordered voltage regulator from FCP ($40 with shipping) will try it.

Disconnect your battery from the car terminals and measure the voltage. What do you measure?

I had my AC module go dark this week and this trick worked to get it back. Cheap, quick, and worth a try before trowing parts at it.

Sounds like a good battery. Next step is to proceed with the advice given. Good luck.
