Oh Goodie!  😂

The rotten wire was on the trigger, not the stator. Unfortunately it was rotten all the way up, but I crimped a new piece on anyway for testing purposes. Still don't have any spark.

Just from resistance testing, it's looking like the trigger, CDI says it should not have continuity to ground, but I am showing some resistance on all wires. I will order one and see what happens, since I need one anyway with the bad wire, I don't trust the repair long-term.

Resistance on the stator was perfect, although that is not definitive.

Resistance (bench test) readings are always sketchy and usually lead people to buy parts that they don't actually need.  DVA output tests are what you can better rely on if you can aquire a peak reading adapter for your voltmeter.

I know it. Unfortunately it's not looking like I'll be able to find a DVA locally, so I'll grab one on eBay.

Even if the trigger was working, it needed to be replaced anyway because of the wire situation. Looked to me like it was sealed, so you can't get in there and solder a new wire onto the windings.

You can actually make a peak reading adapter with cheap parts from Radio Shack and use it with any digital voltmeter.   I have the diagram and parts list somewhere, but I'm sure if you just Google it it's there.

Here's Stu walking you through it...

Radioshack? Shoot, I didn't even think there was any of those left around. Is there still one in business somewhere?

Used to be one in Bolivar, but they closed it a few years ago.

Hell I dunno, I'm still living in the '90's 🙄

Let me just say.... Anywhere that sells switches, resistors, capacitors, and such.

If Radio Shack is no more then I'm sad.  Not that I ever need anything from there, but it was a cool niche store.

I was able to rig up something with parts from Micro center. I was not able to find a single high voltage cap, but found a pair of 200v caps that I placed in series.

The stator is reading very low, about 5 volts on both wires connected, and closer to 10 disconnected.

The trigger was within spec at a little more than 1 volt when tested to engine ground, however when connected with the black/white (which I believe was the rotten wire I repaired earlier), the readings were low.

Any thoughts Wrench?

What is your coil primary readings?  (green to ground on all 3 ignition coils with everything hooked up)

How "low" was the trigger output?  It actually only takes 0.4v to fire the switch box.

Not getting anything to the coils.

Trigger output is somewhere around 2.5v, but it keeps climbing the longer I crank it. If I held it long enough it may climb to 4 volts (the CDI spec), but I don't want to burn up my water pump, probably because the capacitors I'm using are larger than recommended. It does not change when disconnected.
