We killed the battery in the car. I think it was because the cigarette lighter was partially pushed in and I know that it was broken to begin with.

I did a leak down test with the battery.

Ignition was off.

All switches were off. and doors closed.

I am still getting a constant drain of 0.13 A at the battery.

Is this about normal for a computer controlled vehicle with an aftermarket stereo with a memory?

I just replaced the battery in the GTO today too!

.13 is alot bro. Had a .02 in the Sunbird and that would kill the battery in 4 days if not started/run. Finally found it was the AMP gauge in my engine compartment making slight contact. There's a guy by me with 2 Fiero's for sale. 1000/best 1800/best they both look in good shape. Busted rear side window in one. Hard to tell more without stopping

I agree that .13A is a lot. Can you unplug the radio or remove the fuse and then do your leak down test again? That would at least let you know if it is the radio (or how much the radio is contributing to the .13A). You could repeat the same steps with other fuses to help identify the offending circuit. Electrical problems are the worst kind of problems to diagnose and solve.

So I figured it out. One the origonal battery we bought the car with was 9 years old. Second the cigarette lighter got stuck in so it was drawing current for three days straight. The radio goes through a reset proceedure every time you cut then add power. This takes about 10 seconds. I should have used aligator clips and not just the probes that I have. I verified this because the truck has the same radio. Once the reset occurs then it drops to between .03 and .02A Which is in line for the Fiero service manual that I found.

Yahoo!!! Progress !!! Slow but sure.
