General Stator question

[gatheringsticks]

I have a 1967 Viking/Chrysler 55 hp Ignition /Alternator with battery and starter outboard.
Can the Stator produce spark on one cylinder but not the other?
Does it have a separate set of wire winding's for each spark plug ?
I have voltage going to one coil but not the other.
I suspect the stator is pooched.
I will test it but I would also like to know about its circuitry.
thx

Re: General Stator question

I know that an 88 125 force stator has a separate set of windings for cyl 1-2, and another set for cyl 3-4, the rest are for AC output, (alt and charging). So, yes, one section can cause no fire/missfires on one or more cyls. But I do not know your setup.

Re: General Stator question

If it has cdi ignition then each cylinder has its own coil to produce about 300v .. why not disconnect each coil and measure its resistance....then measure the output volts when cranking ....here is the instruction manual

Missed the 1967 bit so it could not be CDI.....simple coil and battery with two sets of contacts..if you have 12v at each coil where they link OK test the coils 3-4ohm for the primary and a few thousand for the secondary ..OK if the coils pass then its flywheel off and check contacts/condenser etc.

Re: General Stator question

Alternator and battery ignition uses the stator to charge the battery and replace the current used to make spark. You can not tell if the stator is bad unless you either run the engine and check for voltage output or disconnect it from the rectifier and check the wires for resistance or grounding. With spark on one cylinder, look elsewhyere for the problem.

Voltage to only one coil means a problem with wiring. Typically, voltage from the ignition switch while in the run position will be split to two coils and is on constantly. The dual points under the flywheel make and break the current to ground thus allowing the coils to produce spark.

At the ignition switch, red is power from the battery (from the engine terminal board) and blue, connected to the "I" terminal is power out to the coils. At the engine terminal board this blue wire is connected to either one or two blue wires or one blue and one brown that go to the positive side of each coil. The negative side of each coil is connected to its respective point set under the flywheel.
