I need some help. my voltage regulator went out and I bought a cut out for a replacement.

My problem is two wires come out of the generator, 1 is the field. I'm not sure what the second wire is, but on my voltage regulator there was a place for each.

On my cut out, I only have two spots. One for the battery and one for the "generator". My question is does the field wire go to the "generator", and if so, where do I hook up the other wire? The battery wiring is the easy part...

Any help would be appreciated.

Do you have a resistor on your light switch? The resister needs to be used in conjunction with the cut-out to prevent blowing your light bulbs. The only way to control the charging rate using a cut-out is to slide the 3rd. brush in your generator. Does your generator have a 3rd. adjustable brush? If you have all of the above, I think you can get it to work by connecting the generator field wire to ground (engine block)and the battery wire to the cut-out? I don't think the generators that were designed for cut-outs had the 2nd. wire.

Generally, the "F" wire from the generator, when a regulator is not used, goes to a two-position light switch, which switches a resistor in and out of the circuit for high and low charging rate.

I think I understand, but how do I then complete the circuit? Do I need to run a second wire from the switch to the "generator" post on the cut out?
