Reply To: OMC Kill-switch question

Well, I have no idea what this would happen either.  Am guessing this is a universal mag engine, not the low tension ignition or mad distributor set up on the old V4s.

I am reading that you connected a switch directly at the engine and it did the same thing.  You are using some sort of toggle switch, correct?  Do you have any pictures of the mag plate wiring?  Perhaps there is a break in the wiring underneath the mag plate somehow occurring at higher RPMs.   Perhaps this toggle switch has a high resistance over the terminals, you might try rigging up a conventional OMC push button set up to see what happens.

In any event, I don’t see any reason why your proposed setup would not work, but primary voltage arcing could be a concern….
