No Spark - 8HP Mercury 1989 2 Stroke - Are these Coil, Stator, and Trigger Readings Good?

Hello,

I'm working on a 1989 8 HP Mercury 2 Stroke that has no spark.

I haven't been able to find out what readings I'm looking for on the coil, stator, or trigger assembly for this motor. Keep in mind these reading are made while the parts are still on the motor. If I need to remove them to make the readings let me know.

Left Coil

Between Positive and Negative Terminals - 0.1 Ohm
Between Positive and Spark Plug Wire - 903 Ohms
Between Negative Spark Plug Wire - 904 Ohms

Right Coil

Between Positive and Negative Terminals - 0.1 Ohm
Between Positive and Spark Plug Wire - 972 Ohms
Between Negative Spark Plug Wire - 973 Ohms

Stator

Between the wires - 3.121k Ohms
Between blk/ylw and ground - 3.257 Ohms
Between blk/wht and ground - 135.7 Ohms

Trigger Assembly

Between the wires - 735
Between brwn/ylw and ground - Nothing
Between brwn/wht and ground - Nothing

Are these readings any good?


I read somewhere I could test the kill switches or kill switch wires, but the instructions were unclear. If anyone can guide me on how to work the wires in order to test the kill switches let me know.

I also read it could be the switch box, but there are zero instructions on how to test the switch box. Anyone know how to go about testing the switch box?


Also, is there anything else I can test for?

www.cdielectronics.com has the info you need. Why did you take it apart? To test the kill switches it is the black/yellow wire. Do a continuity test on both switches. You should have first tested the kill switches. Do you have the switchbox?

Thanks! According to the guides, both coils and stator are out of spec. Yikes.

As for taking it apart, I did that because I mainly just like to take things apart lol because I like to look at what I'm dealing with. It wasn't hard, and I may need to switch out the stator or switch box anyway?

For the switches, you said I am testing the continuity of the black and yellow wire? This is the wire that goes to the stator I thought? Also, in terms of continuity, where should the other lead touch to test for this?

I do have the switchbox. Do you know how to test it by chance?
