25 mercury with no fire, stator and trigger testing results included. switchbox?

[arkansashunter]

Hello,

First off thank you for reading this thread. the forum has already helped so much.

My motor has no fire getting to the coils

It is a manual start 1992

Ran test on the stator and trigger and the results are as follows (im not sure if i had all the settings just right on my meter, electric guy i am not, so its safe to assume the decimal points could be off... The numbers seem to line up with my book tho... )

Stator

Black white to ground 142

Black yellow to ground 3.17
Black yellow to black white 3.05

Trigger

Brown yellow to brown .80 (20k setting on meter)

Would this mean that it has to be the switch box, assuming the kill switches are good (i disconnected the kill plug from the switch box and pulled the cord and it still had no spark at either plug)

If the switchbox is bad and i replace it will it be compatible with putting electric start on the motor? I do not have the recharging stator (the red one).

I do have a junk 99 that all the electronics work on tho and was going to rob the electric start components of it to convert mine.

Thank you

so do these test results point to a bad switchbox? do i need to run any further test before dropping 100$ on a new one?

So would these test results rule out a bad stator. Or trigger and point toward the switchbox?

Update.

I know that the newer switchboxes with the green stator wires are not made to function with the pre 94 motors due to the spark advance (i think this is right.)

That being said i have a newer motor with what i know is a working box. So i put the newer box on my none firing 1992, it fired off one coil and did not fire off the other. I expected this from the start so i swapped the coil leads and it reversed the fire to the other plug. Basically both coils work and the stator and trigger work so i guess that leaves no other culprit than the switchbox.

Sound Correct?

i'm not exactly sure why an expert hasnt chimed in, but i'd have to say I agree with you. switchbox.

how did you test your stator wiring? Did you use a mutimeter and DVA or do you have the right meter. I made a DVA(Digital Volt Adapter) but i dont think it works.
