My new (to me) ‘73 CT3 came with a dead electrical system and an odd sleeve of 6 snipped wires sticking out back of the headlight. Ive done what I can to figure out what they are for but I can’t make compete sense of it. I’d like figure out how to reconnect the wiring to stock and cap any live wires.

The only other unbonded wires up front are the (male) wire for the tach guage light -blue- and two turn signal wires (male)- dark brown and green. The neutral light is gone from the tach.



Here’s what I could trace:

Dark green & dark brown are blinkers left & right. Light brown should be live dc volts after the main switch. Light blue neutral. Darker blue i think is ac power to the instrument bulbs plus tail light on models with ac tail light.. Orange has me stuffed at the mo. That's all from long term memory 40 years ago. Can't remember what happened yesterday lol. Someone will chime in & correct me now i've started it. Is those cut off wires what goes up to the blinker--dip--horn switch?--orange could be horn wire to the button but don't think that makes sense. CT1 will be the same. Follow this link & scroll down to the bottom. Bit slow to load on my computer but page 98 of 99. Maybe Orange isn't orange & just the angle of the photo. Assuming yours is 6 volt of course which it should be unless its an AT1 electric start with a 175 top end fitted. This diagram shows blue to the tail light as we have here in NZ but thought US models had battery powered tail light or maybe only in one key position for when parked on the road. I dunno--carry on. Cheers.

That brown [ 6 volt even when Off] must be connected to a red somewhere [ RED FROM BATTERY, ]. . .as he says , its a switched 6 volt,,[ ignition ON].

Can't say that I'm familiar with that model, but with the wires for the indicators (dark brown and dark green) and lights (blue) there, my guess would be that they originated in the left hand switchgear - is that all present and correct (I can see the pink for the horn elsewhere in the headlamp bowl)?

Perhaps bin that lot and get some replacement left hand switches?
