I'm an idiot (F4i ignition wiring)
Yeah, that's right. I'm stupid.
I'm building an F4i for the track (not why I'm stupid) and removed the ignition key switch assembly to replace it with a toggle switch as I have done with my two previous race bikes.
Unlike my other two bikes, the F4i has a diode in the ignition assembly that sends a signal straight back to the ECU. I'm not sure what signal it's looking for, but it the fuel pump won't run and the starter won't turn if the signal is missing.
In my attempts to get the bike running I tried soldering the diode into the wiring (both polarities). This didn't work. I then tried connecting that particular wire in the harness (pink, no stripe) to ground. Nothing. Then to line voltage (12VDC). Still nothing.
Now completely baffled I called a friend of mine who's an electrical engineer. She tells me that the diode could have been a Zener type and that I might have fried a chip in the ECU by connecting the wire to line voltage. CRAP!
Anybody out successfully replced the ignition key switch assembly? Anyone know what the deal is with that diode?
