I am new to the forum so please be gentle and if I am posting in the wrong area please tell me and let me know where I should post this.
I did some trading for this bike and was lied to about it running when these people got it. There are things on it that show it has not ran it a very long time.
It is a 1994 Polaris 300 4X4 W948130 with no spark. I have read the post here, watched the youtube videos and I'm usually a petty good mechanic but this one has me stumped.
I have replaced the stator components (the charging coil and the exciter coil but not the plate they bolt on to) new CDI and three different new coils. I checked the magnets inside the flywheel because one of them looked replaced. They all had good pull on a screwdriver (the way you use to check the ones in a outboard motor) and were orientated north, south, north, south as they should be.
If you unplug the exciter coil plug (blk/r, brn/w, w) White shows good continuity to ground. Blk/r to ground shows no continuity and about 4vac cranking. brn/w to ground shows no continuity and about 4vac cranking. blk/r to brn/w cranking shows initial surge around 28 vac then drops to a steady 13 vac. Cranking speed is with plug removed to get a better crank speed and less strain on the starter and battery.
Unplugging the CDI to coil wire (blu) there is no ground continuity and output is 13vac.
Coil input shows 13vac but there is no output to the spark plug. The plug wire has good continuity and so does the plug cap.
All resistance test on new components were within specks and all test were done with the black wire from the CDI disconnected. All continuity checks from battery negative to frame or engine, and frame to engine show good.
Reviewing some of the youtube videos they show 80 to 100 vac being sent from the exciter coil to the CDI???
