Hi everybody!
I have a 1986 fz600 (not fzr, but I'm hoping you guys can help anyway) that I'm in the process of getting running. So far I've cleaned the carbs and changed the oil. I'm at the point where I think she'd fire up if she'd turn over, but she won't. The funny thing is, that during the process of checking the charge in the battery when I purchased the bike, the engine was able to crank under its own power but now it seems like that is not the case. I've been going through the various electrical systems and so far have found nothing to be at fault, and the starter is able to crank the engine but its only when I short the starter solenoid itself (without spark of course). The only electrical component that was removed and then re-installed after the initial crank-over was the ignition module. Although I'm unfamiliar with transistorized ignition systems, I don't see how that could be the issue?
The start button causes the oil light to turn on, so I know that the start button circuit is not at fault. All the wires from the run switch, the light circuit, kickstand circuit and clutch circuit have been similarly tested with a multi-meter and they are all good. All these wires run through the flasher relay, and so far there is nothing to indicate that it is at fault either.
So far, I know that something is impeding the circuit between the start button and the starter solenoid but I'm running out of troubleshooting ideas, except to buy a full new set of mysterious black boxes (ignition box, diode box, flasher relay) when the ones I have are probably good anyway.
If anybody has any suggestion on how to narrow this problem, that would be much appreciated.
