Regulator question

[Jackman]

Does a Cub regulator have a ground wire? where are the grounding points?

[tst]

it grounds where it bolts to the engine, the body of the regulator most of the time has a small ground strap to the base of the unit

Thanks Tim , I guess the wire that I can't find a home for is an an add on from a previous owner , ( I'am holding the mystery wire in the pic, one end to the regulator mounting bolt and the other end undetermined

[tst]

the owners manual has the wire chart in it showing where the they need to go

Sounds like a safe assumption. Grounding wires under mounting bolts don't sound like original design anywhere on a Cub.
Maybe grounding out the generator to get it to put out full all the time?

Not unusual for an ammeter to not work after painting a tractor due to it not getting a good ground through the paint, and a wire being run from one bolt of the ammeter to a good ground point, or even back to the ground side of the battery.
