85 hp Force Spark Problems

[Cessage]

Hey guys- been reading the other posts, you all seem really knowledgeable.

I have an 1985 85hp Force 3 cylinder outboard. Only cylinder #1 is getting spark.

It has 2 CD ignition units and 3 coils. Each CD has 2 output wires. CD#1 Wire #1 fires cylinder 1, but when I hook it to coils 2 & 3, they spark good. So the coils are ok, right? Wire #2 on the first CD unit was hooked to Coil #2 but would not fire any coil. Neither output wire on CD unit #2 would spark any coil.

See illustration

So are both CD units bad or could it be a Stator that can't give enough to get past cylinder #1?

I appreciate any help you guys might have for me.

First I would get a Clymer manual and do some testing. You need a specialized multimeter to do voltage tests, but you can do some resistance tests with a basic meter. Test the stator output wires (blue and yellow) for resistance. You should get something like 650-700 ohms between the yellow and blue.

Thanks 4runner, i tested it and it pegs out at zero whether cranking or not. Does that mean a short?
