Bigdog,

So, if this works, should I then run a lead from the F terminal to the ignition switch instead of the L lead?

No! From the F terminal to ground. This by-passes the regulator and puts the generator to full output. If it doesn't charge then, the generator is probably bad. The L terminal to the ignition switch is correct. Then from that point on the ignition switch, a jumper goes to the light switch . The other side of the ignition switch goes to the coil minus terminal.

Big dog is correct about the L terminal, When you said it was on top of the generator I had F terminal in my mind. Guess I'm getting senile, but I didn't think any of the cubs came with a regulator on top of the generators, only cutouts.

John, I'm thinking someone replaced a cut-out with a regulator and mounted it where the cut-out was.

The Cub was originally a magneto ignition. The way the story goes, someone replaced it with full battery ignition in the 60's by replacing the original cutout which was on top of the generator with a full voltage regulator and retrofitting an IH automotive coil next to it. It works fine enough (if I can get the darned thing to charge) :wink: but some day, I'd like to convert back to magneto.

The wife had the bull whip out last night so I didn't get a chance to play. Hopefully I'll try the grounding tests tonight.

Will post again if the gen fails to operate.

Well,

I've done all of my grounding checks as suggested and I can't get the ammeter to show a charge. My next step will be to pull the generator and inspect :( . Thanks for all of your help everyone. I'll continue to post to update.
