Hi I have a 94 Cadillac Deville 4.9L and im trying to figure out with cable on my alternator is the power cable and which one is the ground. I have included a pic to help.
There is NO GROUND WIRE!!!! see the bat on the alternator next to the 1/2 nut? that means battery..... ADDED: Oh.....son of a gun, there is a ground wire....That's redundant...
Yes,,, the hot wire is on the back of the Alternator,, The ground is on the side.
usually only power wires run to the alternator, most arent grounded by a wire, they are grounded through their case and the mounting brakets to the engine, but all charging systems are a little different. I see your ground runs to the mounting bolt, and so that wire that goes to the mounting bolt on the alternator would be your ground wire to the battery. the large wire on the back of the alternator in your picture has BAT beside it, that is the wire that would be the power wire back out to the battery. i would suggest to get a haynes or chilton manual for this specific vehicle if your not sure of things such as this.
The ground is one on the side. ADDED: hahahhahaha , IMNid, that was funny :)
The power cable is the fat one.
