Hey everyone I am new to the forum but was hoping to get a little help from some of the pro's.

I have a 1993 15 hp Mercury, last time I used the motor it started fine and shortly after it started it died and I have had no spark after that. So far I have ruled out the kill switches, I have done a ohm check on the stator and it is within specs, I have a hard time believing that both coils would go a once. My question is what are the best and most reliable checks I can do on the trigger and the switch box. Any other ideas would be appreciated too.




Thanks for your time and responses

On CD ign. the best and most reliable tests are done with a DVA meter. With a ohm meter you may also check the trigger winding for continuity

I will check the trigger from wire to wire, what is the specs for the resistance?

Thanks CTS

Thanks Laddies, I checked for continuity through the trigger and it appears to be open. I guess I will order a new trigger and give it a try. You wouldn't happen to know the part number for the trigger or where to find it?

Serial #0D256609
