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?

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

Does this mean the Voltmeter comes from something completly different?
I will wire as per prescribed above today and update
THANK YOU Vader and Tim

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.
