Need ignition specialist. This thing is driving me nuts

1995 90HP 3cyl. Hasn't done this in a while but finally happen again. Running good, stop to fish for about an hour and won't restart. Not getting fire to any plug. Removed kill switch wire and still no fire. Get towed back and trying to start it several times during the trip back but no go. Get it home, DVA while cranking on blue 210V and red was 40V. Everything ohms out good except trigger seems fishy. Getting 960 ohms on white wire and 1250 on each purple and brown. 8V on white and 5-6V on purple and brown while cranking. Hook everything back up and it started. I blew switch box about 3 boatings ago where I had no spark on #1 cylinder. Even tho the trigger ohms within specs, I'm thinking that lower one may be shorting out when hot and possibly causing issue. Anything else I might need to check?

Sounds more like stator is getting hot and failing, take meter tolake and test when it fails. Do you have a volt gauge as if overcharging rectifier/reg could be bad overheating stator.

Wish I had my meter when it happened. Voltage gauge reads right on 14 once a little above an idle and never seen it go any higher. I noticed that the tach was reading RPM while cranking when it wouldn't start. I already bought a used trigger for it and all 3 circuits measure around 1250 ohms. I have noticed the tach to stick at different rpm's sometimes say at 2200 and not increase until it hits maybe 4K. I thought it was this cheap chinese unit but maybe something is freaking it out. So how can the charge circuit affect the running operation? My understanding was the stator has a high, a low (red and blue) and the charge circuit (2 yellow wires going to rectifier). The stator is a cdi replacement and was replaced probably about 8-10 years ago according to previous owner and ohms out perfect on the red and blue according to their specs.

If rectifier/reg is failing/bad it sorta turns the battery charging windings into a heating element, the stator get hot and breaks down as the heat effects all windings...

OK...since I'm pulling flywheel to change the trigger....stator is getting changed as well

Remove the tacho.

Remove the tacho.

I guess something to consider if it happens again but just for piece of mind, since i'm pulling flywheel to change trigger, stator is getting changed too!!

Ok, so I was reading cdi trouble shooting chart. No spark on any cylinder, one of the tests is to remove the yellow wires from rectifier and see if you get spark, if so, replace rectifier. I thought the 2 yellow wires going from stator to rectifier are for the charging. Can anyone explain how this can affect the ignition system? The switch box doesn't have any 12V power up wire from what I can see. I'm guessing it gets power from the red and blue wires from stator. Maybe these wires tie to the yellow some kind of way?
