New guy, but not new to bikes. Looking for some help. I have a hand me down ex police 1964 servi-car. The switch one the upper throttle side is missing.
Heres the odd part, I have 4 wires sticking out of the bars. Most pictures I find are of a 2 wire push button switch.
I can't find a 4 wire switch that would go there.
would anyone have a picture of what belongs there? Or even better.....a link to the part i need?
Thanks!

 

police duty had installs done at the dealer for the most part - so no wire diagram no parts book visual

siren maybe - 2 way radio on and off - flasher police lights everybody blinking -- its a guess

its could also be electric start and the relay routed that way a little dumb but it was dealer guys

 

Sounds like I'll have to test each circuit and see what each one does.

 

Its age we would just buy a new wire harness and the ones available are fit everything and it needs extras like tail lights all the starter stuff and if you have blinkers them too

50 years and cotton covered wiring is a fire looking to spoil that day

 

Eventually. Right now I still need the switch.
I did locate the old one, seem it's horn and hi/lo beam. Currently no spark so I'll be starting there.

 

check -power at the points by open and closing using a test light its direct from the key on position

 

If you are are not restoring her back to Police duty, I would try and remove as much of the 'extra" wiring as possible. Extra wires just going to confuse the issue. Overall re-wiring the entire bike is not the worst job, and you may fix two other problems along the way. In this vintage, wiring can be a real problem from age and previous chubby fingers. Good luck, we like pictures.

 

Got her going. Cleaned the points and she runs, back to finding the switch I need and the correct regulator.

 

Here is what I'm working on

 

my guess its 12 volts
