Headlight/Starter interrupter
« on: April 01, 2008, 07:24:30 PM »
Bike is a 76 550'K.

I know my bike "stops" the headlight when the starter is activated. However does it also stop the tach/speedo illumination lights and brake running light too?

If the three wires (Yellow/red, Black, Black/red) where left unplugged at the starter switch would this be causing my missing headlight, speedo/tach light, tail light running light to be off when the ignition is turned on.

Or is my problem not have to do with the starter button?

Swapped the headlight bucket a while back and ended up with a little short brown/white with black sleeve on one end jumper wire. also had no lights. also didn't show on the wiring diagram I had handy. Plugged the black sleeved end into black wire and tada! let there be light. Has someone been in there lately? ;)

Or....have you recently replaced the starter solenoid with the one from an earlier bike? The K4-later 750, for example, had dual-contact posts on the starter solenoid that made contact for the lights while the starter was not running, opening that circuit when the start relay was pulled in. If the wire(s) get loose, dirty, corroded or not plugged together when the relay gets replaced, the lights will go out....

Just my $.02 worth...

I have been switching back and forth with the original solenoid to the bike  and one off a 77-78 550. I believe they are the "dual post" types. Interestingly today my solenoid crapped out on me. It was the original one.

Although it is more probable that its just wired wrong (My head light bucket has been open for about 3 weeks now)  considering I recently untangled and reattached all the connection in a nice orderly fashion as compared to the mess it was.

However I will recheck all the connection on the solenoid just to be sure. Thanks for the help.
