    1925 Henderson Wiring Daigram

    Does anyone have a wiring diagram for a 1925 Henderson? Mostly need to know if it is a positive ground or a negative ground??
    Thank you in advance,

    It is a negative ground system. One interesting thing is that the ground wire from the battery runs up to one leg of the ammeter, the longer one if you have the right ammeter. The long stud is insulated from the ammeter bracket, the short stud is not and that connection to the bracket and then the frame becomes the ground circuit. I made drawings of that set up, I'll try and post them. The wiring diagram is in Rich Schultz's Henderson book, if you don't have one, you should.
