Question about 1995 Pontiac Grand Am

1 Answer

1995 Grand Am GT-3.1 Ltr. V-6: I am needing a wiring diagram for the alternator charging circuit. I have a short somewhere and before I found a burnt wire coming from the alternator. But before getting too deep I want to be sure of exactly where and which wires I think I should be looking at. Alternator checked good to specs. BUT the red battery wire coming out of the back of the alternator is TOOO hot to touch. Could this be a faulty ground?

Most likely...seems like you have a handle on it. There may be wiring diagrams available, for example Chiltons manuals...To my knowledge there exists no "internal" wiring diagrams for alternators of any make.
Good Luck

1995 Mercury Grand Marquis blowing 40 amp fuse as soon as I turn on ignition


It will help if you can identify the 40 Amp fuse that is being toasted when the key is turned.

I looked briefly at a fusebox diagram and found 3 circuits protected by a 40 Amp fuse. The Lamp circuit protects several circuits which have smaller rated fuses on each separate wire. The 40 Amp protection seems to be a safeguard if all the smaller circuits are active in total. Turning off the automatic headlights, should reduce power drain.

The next circuit is the Rear window defroster. Can easily pull 40 Amps, but once the 40 Amp fuse breaks, it should have no effect on the engine.

The last circuit, on the cars with Trailer Tow or Police package has a
40 Amp fuse on the Battery charge Relay. This is a remote possibility. But the engine should be able to run without an Alternator for several minutes using Battery power.

Have them check the fuel pressure. The Inertia switch could have tripped while the car was being repaired. It does not explain the wiring short, but can explain the no start condition.

Again, if the same 40 Amp circuit is overloading, identify the circuit with the fuse box diagram.

96 grand caravan 3.3l battery not staying charged. new serpintine belt, batterty, pulleys, and alternator tested ok several times. Also new computer installed and no fuses are blown. Should I replace the...


if alternator tested fine the wire on the back of the alternator is not getting a circuit back to the battery to charge it.
You can run a wire from the back of the alternator to the battery positive post and it will charge the battery.
I have done that several times on dodges because of ammeter gauge in dash being burnt out.
With the ammeter gauge burnt out it breaks the circuit from the alternator to the battery and the battery does not get charged.

Not charging


Possibly a fusible link somewhere in the circuit has burned through and disconnected the circuit.A wiring diagram would be needed to look for the location of any fusible links Ohms check the wires involved in the alternator charging circuit to verify continuity.
