Can anybody out there give me the wiring diagram for the junction box/instrument box for a Farmall B. I am mostly concerned with the light switch hook up. I cant get it to the regulate the charging system with the L and H positions.

Thanks for any help.

The housing and the sw must be grounded to the steering post. Mite have to clean things up. I use a meter to check for ground. With engine running ground the field terminal on the generator to check the gen. Also if the original gen type is still there the third brush can be adjusted for current output.

Thanks so much. That really help to get the old b back to charging 5 amps instead of a straight 15.

Thanks Again.
