if its an ampmeter, best of luck.
there is probably a common 12v for the cluster that also puts 12v on the fuel guage. theres no way around it, if you want it to work, you gotta get 12v to it. i used an autometer in my car.

Yes its just a volt meter(stock) and I have an aftermarket one... but on the charging circuit you need to have resitance in that lead I'm talkin about either a light or the resistor, or both... or it will not charge.

I did not do it went I did my system the first time and Richard Pedersen pointed it out, added the resistor and it worked.

It was over two years ago, so I don't remember much else...

thats the sence wire for the field coil. mine is on a 12v switched source w/ a big ass 2watt resistor in it.

Looks like I better order two gauges (assuming I want a fuel gauge). Thanks for the info on the resistor. I read that without it or a light it would not charge like you said David. I did not know it needed to be a switched source of power.

Thanks

You would first time you tested your required master cut-off switch.

and keep in mind that if you do run a light only and it burns out, it will stop charging... I recommend running both, or just the resistor.

I found this site.

and this one really helps.

It has everything I need. I can bring power to the red with lt green, ground the black, hook up the fuel gauge wire (yellow with white) and the volt meter to lt green with red and the volt meter and fuel gauge should work. I will tape up the other wires that could be hot and should be good to go.
