I spent 4 hours circuit-testing my motorcycle's starter system. Everything seems normal. I suspect the junction (fuse) box is faulty ... right?
You helped me reinstall the starter solenoid
on my 1993 Kawasaki Ninja ZX600C, but now something else in the starter circuit is acting up.
Pushing the starter button (kill switch in Run, transmission in neutral, kickstand up, battery charged) gets nothing: no cranking, no clicking, no nothing.
I thought the starter switch might have failed, so I checked it with my multimeter: it's fine. So I checked all the rest of the starter-related wiring I could get my hands, er, probes
on, using the Haynes repair manual's diagrams as a guide: everything seems correct.
When I jump the terminals at the starter solenoid, the starter will turn and the engine will fire.
The kill switch is operating normally.
The running lights, headlights, turn signals, brake lights, and instrument cluster are all working correctly.
The battery's fine, and everything's grounding correctly.
Frustrating, until I remembered two other points I'd neglected:
1. The horn quit working at the same time as the starting system. I checked the switch: it's working normally.
2. The junction box used to click momentarily when I depressed the starter switch. It doesn't now.
So here's what I'm thinking: the junction box has failed. Does that sound logical? Likely? I could just order another one and find out, but Kawasaki wants $150 for a new one, and even eBay doesn't get better than about $50 for a used (i.e. questionable) one.
(And yes, I know I could ask this question at one of the motorcycle forums, but AskMF folks tend to provide more useful responses than the average 18-year-old forum trolls.)
