Where's my electrical gremlins? Wont start!

OK

1 you've changed the ignition switch

2 changed the starter relay

3 it cranks seemingly every time when you jumper the starter relay?

This sounds like the circuit that energizes the start relay which is very simple

You have a dedicated "start" wire coming off the ignition switch which is traditionally yellow/ yellow tracer

(These did NOT have seat belt interlocks, did they?)

The start wire comes directly from the IGN switch, through the bulkhead, and ends on one of the "push on" terminals of the start relay.

The remaining terminal of the start relay goes down to the center terminal of your neutral safety switch, and sees a ground in either park or neutral.

SO identify the two wires, normally yellow and brown, or refer to your wiring diagram

Remove the one going to the NSS, (should be the only one going down behind the engine) and clip lead the terminal of the relay you just unhooked.

CAREFUL It will now crank and start in ANY gear!!!

Now try it and start/ drive/ restart it long enough to determine IF that hid the problem.

If so, a bad NSS, bad connector, or broken wiring from the NSS up to the relay

If this does NOT hide the problem, and IF you do not have seat belt interlocks, it probably is a bad connection right in the bulkhead connector.

I was out riding my trike today

(I'm not nearly as cranky as I look. This was a self timer on the camera, only 10 seconds to get from the camera and "posed")
