Hello all,

I'm installing the wiring harness on my Mach 1 replica, and it's going reasonably well. My plan is to retain the stock regulator, which I've taken apart and cleaned up; it tests OK electrically.

When the base bike ('67 Monza) arrived, its regulator was bolted below the frame strap - but it interferes with the battery there, so that's wrong. It clearly needs to go on the top of the strap, inside the seat. The factory manual photos show it there, with the wiring connectors facing backwards. But it looks like the wiring fits better, with easier routing, if the regulator connectors face forwards.

What's the normal/proper/best orientation?

Thanks,

Dave

I found my M1 with the regulator on the top of the strap, connectors facing rearward.

Tell me about the SAFA battery... Where can I get one like that? Thanks

Rearward facing must be better to keep the water out.

Great point! I would bet you are exactly correct with that theory.

Thanks everyone, I've managed to get it connected in the rear-facing position. Today was spent debugging the wiring.

My wiring diagram shows an unused terminal in the headlight block, which turned out to be connected to the headlamp socket ground wire (black). Into it was plugged one of the three black wires from the harness (outstanding use of color coding there). After I sorted out which black wire went to which terminal, still no light. It turned out that for some reason the black wire which, by process of elimination, went to the undocumented terminal, was not a ground. Don't know if it was intended to be, or I have a hybrid wiring harness someone assembled.

Anyway, I replaced it with a direct frame ground and it appears to all work now. (Although I did have to learn the exact position of the key switch that turns everything on; not obvious to the novice).

Time for a glass of wine. Possibly several.
