electrical charging system problem
I got my alternator and battery tested, and they are both fine. I checked the main fuse and it is fine as well as the cgs fuse under the hood near the main fuse. Does any body know where the charging system fuse (#6) is? I think its the 15 amp one in the fuse box under the hood labeled cgs (or something like that).
I can jump start the car and it will run fine. But the battery is dead when I try to restart the car even after the car has been running for an hour with none of the accessories on. The battery is brand new and tested fine at a shop other than where I bought the battery.
Any ideas? Fuse maybe?

I have an aftermarket audio amplifiers connected and switched on by the stock stereo amplifier turnon lead. I turned off the curcuit breaker that supplies the power to the amps and the alternator is still not charging the battery enough to start the car.

Well, lately my battery has been charging just fine. After I took my alternator to the shop to get it tested, I guess I must have tighted up a weak electrical connection or something when I reinstalled it.
I measured the battery at over 13 volts with the car sitting overnight, then I started the car and measured the battery voltage at over 14.5 volts. So I guess and hope that the charging system is ok now.
Any body else ever run into this?

I JUST got my CL out of the shop after it dying day after day after day last week. I replaced the battery and it still died overnight. I then replaced the alternator. (ok, paid to have it replaced). Car still died overnight. Took out new battery and got it charged @ Checkers. They said the battery was "good." Car ran fine and then the next morning, same thing. Turns out that I had a "drain" on my battery from an electrical short - specifically, the trunk light. Now that the trunk light short is fixed, I haven't had any problems maintaining a full charged and running vehicle. I would recommend running a diagnostic and search for shorts.
