Duffster,

I'm still digging, but the voltmeter shouldn't be connected in series with anything. Connect it to a fuse as you have diagrammed and the negative terminal to chassis ground.

Your alternator appears to have more wires/connections than it should. What year is the alternator?

1988 altenator...suprising i have something from 88 on the car https://www.thirdgen.org/messageforum3/wink.gif
the 'B' connection is the big bolt-on cable to the battery...the other 3 are in the plug...oh....POST # 500 https://www.thirdgen.org/messageforum3/biggrin.gif

The diagram you showed is correct, except for the following:

Move the source for the S terminal from the B wire at the alt to the large lug on the starter solenoid - add a fusible link there, too - they are available from Pep Boys. The S wire is the voltage regulator sense input & should be placed at the power distribution point.

The L terminal goes to one side of the alternator "idiot light" in the cluster (not a volt meter). The other side of the light goes to the gauges fuse (+12 volt power in crank and run).

The F terminal cannot be powered by the same set of contacts (internal to the ign switch unit) as the L terminal. It should be powered from the "hot only in run" output from the ign switch - some of the things that this output usually powers are the A/C, blower motor, & windows.

Here are the alt pin defenitions:

B = Battery
S = Sense
F = Field
L = Light

NIFTY-NEATO-KEEN!!!
Does this mean the Voltmeter comes from something completly different?
I will wire as per prescribed above today and update https://www.thirdgen.org/messageforum3/smile.gif
THANK YOU Vader and Tim https://www.thirdgen.org/messageforum3/biggrin.gif

Vader's right, the voltmeter "+" terminal goes to the gauges fuse & the voltmeter "-" terminal goes to chassis ground.

I think my sense wire on the alternator is the problem with my car not charging. Can I just rewire the sense wire and where should I wire it to? I have a 3-wire 140amp alternator.
