Ignition troubles

[spareparts]

sounds like stator, get a dva meter and check all the outputs

I just had a bad stator but it was effecting high speed, BS checked all with Volt meter and it was indeed bad.

Rechecked my readings today and one of stator coils is open and the other is real high. Looks like a stator is going to be in order.

Another question, while I'm at it should I replace the trigger since I will be right there? Should I go with CDI parts or Merc. Is one better then the other?

Thanks for the replies,

RAPAIR is the reccomended brand by most. IIRC RAPAIR is made by CDI as well.

ck all related, my rectifier was burned also when we went to replace the stator, we did nothing to the trigger.

triggers dont normally give the problems that stators do. I'd leave it alone. If you feel like spending some extra money, pick up fresh switch boxes, they seem to follow stators going out. Old switch boxes can cause irregular time events that can lead to engine damage, Theres a capacitor in the bias circut that stabilizes the voltage for consistant timing. the Idle stabilizer on some models varies the voltage in the capacitor to change the actual timing. I've got a good friend that has forgot more than I will ever know about mercurys. He will not rebuild an engine unless it gets new switch boxes(always replace them as a pair). he also recomends replacing them if they are more than 10 years old as a preventative measure.

Well my new parts should be here today. Last night I checked some of my wires and grounds. I found a bad ground wire to #3 coil and several suspect wires from the switches to the coils. When all is said and done I hope this thing will run like a scalled dog.
