I picked up someone’s abandoned project bike. A 1980 xs650 with electric start ignition. Was running when i got it. But A quick look at the harness shows a mangled mess of custom wires and sloppy component deletions. With the direction I’m going on this project I’ve decided an electronics overhaul was first on the list.
ive never really fucked around with bike electronics, other than some minor relocations and repairs. But I’ve decided to completely redo this from scratch. starting with an 8pin tc bros simplified harness and adding from there, basic tail and headlamps, speedo, keeping the electric start but removing the tach, excess warning lights, unneeded safety relays etc...
Im sure I’ll have some questions about picking the correct wiring diagram but for now, I’m trying to I’d some of the parts/components I have as I try to understand how all this works. This is my first XS and like I said the first time I’ve ever dove this deep into the electric components.
So here’s some things on my bike I’d like explained or identified. (After spending hours looking at various harness diagrams I’ve grown less confident in what I’m starting with,)
this thing with metal humps. What does it do? And what’s it referred to in wiring diagrams?
little black box near the coil, what’s it called?
What does this do and is it needed if I’m just running headlights and tail? (I’ll be keeping a battery if that matters)
Is this the stock alternator/charging system? Still trying to determine what mods have already been made.
This last pic, this is the rectifier/regulator combo yes?
