  1. 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
  2. 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
  3. 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
  4. No, tested ohms then put my drill on the recoil starter bolt and tested the pick up for the pulse to the cdi
  5. 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?
  6. I've tested and retested everything from the wiring harness (3 times, OMG what a time consuming pain), put every part except stator and pulse coil on my buddies running 300 so it's either Gremlins or the pick-up coil. Almost worth the oil and gaskets to try that.So can a stator be putting out power yet not activate the pick-up coil? Is that possible? If it's wierd it'll happen to me, true story.
  7. Yep new regulator and coil will fire all day on my buddies 300. Put it on last time I was working on it and let it run for 45 minutes or so to see if when the coil got hot it would mess up, it didn't. Ran fine.
  8. Cranked it over using a drill (in reverse) and put my multimeter on DC volts and at about 650 rpm all it read was .01
  9. Ok, so as I said, my rides been pull start for a while which makes some stuff harder to check but, finally got some spare time to get back to it and decided to take the recoil starter cover off and hook up a drill with a 14mm socket and pulled my spark plug so I could crank it over while testing stuff. Here's what I found out... pulse coil isn't sending a signal to the CDI. Tested the stator and it's putting out 14.89-15.74 each wire ac volts. Ohmed the pickup at 0.43 set on 20k. So at 10k would that be 215? Or 430? They're both new from caltric and you can't adjust the air gap it's a set it and go part. Could the magnet on the stator that fires the pulse coil be bad but the stator still produce power? I'm assuming they can since that's a totally different magnet from the field magnet
  10. Ok so I dug out my old analog multimeter that does 1 and 10 and got 485 ohms at the pick up coil, it says 390-590 so it ohms good, not trash like the cheap cdi I bought last year that was broke from the day it was made. The stator gives me wild fluctuations, from 0 to .4 ohms in like a second and only holds steady at 0. Thinking when ol boy put my new pick up coil in he didn't check the stator, I can get one cheap on Amazon from caltric.
  11. I get 001 ohms on the stator on every wire at 2000 and 1.0 at 200. I'm assuming that taking that down exponentially to 1 on a meter would be .005 ohms, way below spec. Houston we have a problem, bad stator I'm thinking unless exponentially dropping my reading is wrong. I'll let y'all know
  12. Part of my problem is my cen-tech meter don't do ohms at 1 or 10 like they keep referring to, mine does 200, 2000, 20k, 200k and 2000k. Time to get a new meter:(
  13. Traced the white power wire to the regulator and all outgoing non-yellow(alternator) wires. My 300 has the 8 wire/ two fat round plugs, one for alternator, one for rectifier.when I checked the harness all where good and subsequent testing showed power levels,(checked against my buddies running 300,) were normal.
