Topic: Defeating the F2 Starter Safety Mechanism

[Patrick]

It's not that I have anything against safety systems. It's only that I am trying to start this bike and I cannot get the starter to respond to the button.

From studying the F2 wiring diagram, it appears to me that the safety system is just an elaborate system designed to deprive the solenoid of juice unless certain conditions are met upstream. It appears that all I have to do to defeat it is to run a hot wire to the input on the solenoid. It appears too simple.

Can anyone confirm?

BTW, I already have checked the starter, the solenoid and the button. For some reason I lose juice between the neutral switch and the diode and I cannot figure out why. It could be the diode, it could be the clutch switch and it could be a bad wire in between. So I cannot get juice to the solenoid through that system. It also may be that the clutch switch in my K5 switch does not recognize the F2 diode or something.

The starter button supplies power to the one side of the energizer coil in the solenoid. The other side of the coil is given ground when either the clutch is pulled in or the trans is in neutral.

Anyway, if you can't make the parts work as you''d like, any way you can provide both power and ground across the solenoid energizer coil will make the starter engage.

As a rule I like to return my bikes to stock operating conditions, like wiring. But I am at the point with this project where my psyche might greatly benefit from the sound of this engine running. I'll figure out why the system isn't working later.

Thanks, TT
