My engine won't stop...

[HughN]

Having got peed off with an early 90's Yamaha-based Mariner-badged 30 Hp I bought a Yamaha one and have transferred starter, etc., across. It starts and runs fine - but won't shut off.

The 'stop' wire is a white one from the CDI unit. The engine should stop when this is shorted to ground - it doesn't.

Could I wire a circuit to short the pulser coil (and would I need a resistor to dump it into) or arrange to put the pulser coil open circuit?

I imagine the white wire shorts something out somewhere inside that potted CDI unit.

Thanks
Hugh

Engines can be strange. In theory the white should stop the engine when grounded. I've never tried so I can't comment. I would try installing a kill switch you know is working to the black/white wires first (at the engine). This eliminates a problem at the rest of the loom. I've never tried shorting the pulsars before, if it happened to me I used the choke to stop. If a new kill switch at the engine works, the fault can be traced to the loom, ignition or kill switch.
