Fellas,
My H is confusing me. I replaced all my cables and bought a new eight volt battery for her. She's got a six volt system-- or so I thought. the problem is is that I cannot get my regulator to come down from 11 V to 9.4-9.6 V charging at wide open. I've tried decreasing spring tension on the contact that is held closed by the spring when it is not charging. I've tried decreasing spring tension on the other contact. I tried increasing the tensions back up. It always remains right around 11 V. I could move the third brush on my generator, but it's charging at the perfect amperage rate of 13-15 Amps. Plus, the third brush is almost four commutator bars away from the other brush. I am assuming that the problem is with my regulator but maybe i need to keep fiddling with the third brush and the regulator.
The reg. appears to be in fairly good condition except that the coils for one of the electromagnets got way too hot one time causing them to slightly sagged away from the core and to change color. I am assuming that those coils are not my problem because the electromagnet is working. I am sure i'll get a differing opinion on that.

Bergen - Most likely your regulator is fried and now has an internal short somewhere. Ordinarily output voltage is highly sensitive even to minor changes in spring tension at the regulator relay (the 2nd relay you messed with). If adjusting that spring caused no change in output voltage, you've found the problem. (The fact there's a partially melted coil winding also indicates the regulator is NG).

Try this to verify for sure: Run the motor at max governor and disconnect the wire from the F terminal at the generator. If the ammeter should drops to near 0 or shows a discharge, the regulator is at fault.

My recommendation: Get a new regulator....it'll be $35 well spent!
