I want to know them all, I'm not postive but I believe I have a ground issue with my car
There are about 20 major grounds, and probably a hundred minor ones. The major ones do have location call outs and diagrams, but that's just a bit much to scan and copy.
Let's be realistic here. Your starter works, so the ground from the body to the engine must be okay and the ground from the body to the battery as well. The alternator's power ground is to the engine. Have you measured the voltage drop between the alternator and the body of the car?
The alternator is controlled (sort of) by the PCM. Grounds to the PCM are probably okay, since the engine runs okay (doesn't it?).
Power from the alternator runs to the battery connection at the starter. Have you measured for voltage drop between the alternator and the stater, with the engine running and as many accessories on as possible?
Pin 3 of the 3 wire connector to the alternator should have full battery voltage on it at all times. Does it? (The red wire.)
Pins 1 and 2 (white/red and gray/red) are the communication lines between the PCM and the alternator. Are those okay?
Is it possible that this new alternator is defective?
Is it possible that the PCM has a fault?
