Hydro, hmmmm...........
He said the click is coming from Starter but I haven't heard it myself.
Maybe to be safe he should pull the plugs and try to turn it over. If the starter turns then, well.........
If the click is coming from the Jbox, what would that be? $140 for a new one or a fuse or replacement relay that could be soldered in?
I'll have to make it over there this week or weekend and bring my stethoscope to try and verify where the click is coming from.
My suggestion today was to try and bump start it but now knowing about the hydro possibility I don't know if I want to do that. I said bump start it and if it runs, run it for 15 minutes or so, then shut off and see if it starts. If no start/no crank, then bump start again and while running hit the starter button and maybe it will rotate enough to get past a weak spot, then shut off and try to start.
Lastly, this bike has around 16,000 miles and is garage kept. I'd be surprised if it was the starter but you never know.
Any electrical gurus out there, you're probably in disbelief at the caveman type approach here, lol.
