No spark on 1993/4 70hp Force

I have a 1994Spectrum with a 70hp Force outboard. I am assuming that the Force is a 1994 as well. I am having trouble getting the engine to start. I was running it one day and then stopped and it wouldn't start up again. After getting it home, I checked for spark on all three spark plug wires with a spark plug tester and didn't get spark on any of them. I found a discussion on here about things to check regarding the stator and the rectifier and tried to follow it but my wiring situation is different. Coming from my stator I have a blue, red, 2 yellow and a black wire. I disconnected the two yellow wires to test the rectifier (no spark). From there I am not sure what to check because the other thread mentioned checking the red and red/white wires together and the blue and blue/white wires together. Since I don't have the corresponding red/white or blue/white, how do I complete the stator testing? Also, I read that you can test the stop circuit by disconnecting the black/yellow stop wires. Where are these? I found a black/yellow wire near the stator wires and assumed that was it.

I added some photos of the stator and other electronic components.

Thanks for the reply Jerry. When I look at the link you sent, my wiring doesn’t match up to what they have there. Maybe I’m missing something here. I am not familiar with boat motors but I like to try and fix things on my own.

Jerry, Since I don’t have the blue/white or red/white wires, how do I test to see if the static is bad?

Using an OHM meter, check the resistance between the Red and the Black stator wires. You should read between 75-90 Ohms. Then check the resistance between the Blue and the Black stator wires. You should be reading 3250 - 3850 Ohms. If your readings are not within the specified range, then your stator is bad.

tganks for the help pnwboat. It turns out the stator is bad after doing the test you suggested. I have one on order and will update after I get it installed.
