Its a ground that goes to the firewall and to the left hand bolt on the alternator bracket.Mine goes from my Power Steering unit bolt to the bolt on the alt as explained, simple ground. The laternator itself has one plug and one power , no single ground wires.
This might mean the ground is isolated from the case of the alternator. In a normal application, the case of the alternator is the ground connection and being bolted to the engine block via a metal bracket, the grounded case of the alternator is electrically connected to the ground lead of the battery which is also connected to the engine block. An isolated ground might indicate the alternator ground is electrically insulated from the alternator case.
a bad ground wire can ruin an alternator by not completing the circuit
check your battery ground and your alternator ground
Low alternator output or weak ground connection. Have the alternator checked.
Yes, if it shorts to ground internally.
Generally the battery ground lead is connected to the engine block and the alternator is bolted to the same block via metal brackets and thus connected electrically to the battery ground.
It grounds itsself when bolted on, The case is the ground
yes theres an braided ground wire that bolts to the transmission bell housing
Refer to your service and user manual on how to change an alternator ground wire on a 1994 Mitsubishi 3000 GT.
There isn't a fuse for the alternator. The alternator is belt driven, and there'll be two lines coming from the alternator - one goes from the alternator positive to battery positive, and the other goes to ground.
There is no ground wire.... it grounds through where it touches the engine
Is the alternator a known good one? You could have a bad rectifier in your alternator causing a short to ground when it is installed.
