Testing help for coil on 99 bayou 300

[Kaj Colum]

Did you get any further with this? Was the stator bad?

[Frank Angerano]

Sure it’s possible, one generates power the other sends a signal to the cdi. Two different parts. I’ve seen pick up coils work until they heat up and then fail.  

[Jeff Comstock]

No what meant was could the magnet on the stator that actually trips the pick-up coil be bad and yet the stator still generate power? I've heard the magnets can get weak if overheated or hit with something?

[Frank Angerano]

I don’t think so. I’ve seen magnets come off that’s about it.   When you have the tester on ohms/continuity and connected to the pick up coil wires did you spin the flywheel slowly past the magnet and see what he tester does ? 

[Jeff Comstock]

No, tested ohms then put my drill on the recoil starter bolt and tested the pick up for the pulse to the cdi

[Frank Angerano]

Disconnect the pick up coil and connect it to the tester and pass the magnet by it slowly and see if it triggers the tester.  

[Jeff Comstock]

You mean on ohms?  

[Frank Angerano]

Ohms is fine I want to see if the magnet triggers the pick up coil.   

[Jeff Comstock]

Sorry took so long to get back, between work and hunting for deer I been tied up. So on 20 volts my meter gets wild swings, from 0.00 to 0.06. if i turn it back instead of going all the way around again i get minus 0.01 then when I go past the pick up I get -0.03.  Thinking that's not normal, only got 0.05 at 20 volts once in bout 45 revolutions going slow as molasses by hand

[Frank Angerano]

So it could be a bad pick up coil if the numbers aren’t good. But without the flywheel spinning and the magnet not near the pick up coil do you get an ohms reading on the two wires ? 

[Jeff Comstock]

Yeah it ohms as good with the magnet on the far side away from the coil but again I get crazy readings when I turn it over, from -0.02 to 6.85 ohms at 20k

[Frank Angerano]

I wouldn’t focus on the irregularities of the spinning readings. The coil is supposed to be tested while it’s not spinning and away from the magnet. It has to be on ohms and you should get pretty much the same number every time you test it. 
If it’s within spec it’s good. Then the same tests should be done on each phase of the stator coil wires. Between phases (wires) and then from each phase to ground for continuity.   If all that comes back good then it’s something else.

Ok, first things first... Happy Thanksgiving everyone and thanks for all the help and support. So, now down to the nitty gritty, found the problem, baby girl is running like brand new. 

The crazy readings I was getting from the pulse coil had the answer. When I bought the new stator and pulse coil from caltric I was really hoping I would be able to fix it, it WAS the coil. Somehow the blue wire got pinched almost in two where the wires go into the motor, just above the rubber gasket. Never would have seen it but for the deciding to chance the stator was bad. 

Wish I knew how to do video thingamabob on here I'd show y'all how sweet she runs

[Frank Angerano]

That’s great news brother. Pinch points hurt in more ways then one. 
RIDE SAFE ! 
Happy thanksgiving.
