Default Re: Battery Drain Issue

He then told me he couldn[t open the fuel door. We both tried but it was locked and would not open even though the doors were unlocked. It just would NOT unlock, so I pulled away to a spot and finally got it open by unlocking the car with the key in the door. By then I couldn't start it due to low battery!!!

I got a jump and got it back to the garage and after much troubleshooting found that there is a 4 ohm ground when FUSE 9 is plugged in.

My next step is to check what the current draw is when the fuse is inserted and the car is shut off. I read here that the normal draw should be less than 55ma so I will post an update once I get that reading. I will pull the siren fuse in the Control module box to at least eliminate that next.

Also, can't seem to locate the ILLUMINATION CONTROL MODULE as I'd like to disconnect that as well.
Any other suggestions welcomed.
So the battery went down that far while messing with the car at the gas station? A 4 ohm load is 3 amps at 12 volts - you are not going to take the battery down THAT far in such a short time with that current.
I agree 3 amps thru that fuse is not right, but I"m having a hard time putting this together.

Was the alternator charging?
How old is the battery?
Have you measured overall current in the ground cable of the battery?
