WR426 no spark...need advice!
Posted August 29, 2012 - 02:24 PM
If I take the plug out and ground it and kick over the bike with the decompressor, I get NO spark.
I checked the coil resistance and resistance of the pick up coil and it was in spec. I can't get a resistance reading on the primary and secondary coils through the CDI...not sure what thats about. I can't get a reading on the primary or secondary coils when I tie into the wires down by the stator.
Is there a way to check if I am getting any power directly from the stator when I kick over the bike? If so, how would I do this and how much volts (DC or AC) should I see when the stator/magneto turn?
I have a YZ426 stator that I checked and the pick up coil (red/white wire) is in spec and I can't get a reading on the primary/secondary coils (brown/blue/pink).
Before I buy another CDI, was trying to see if I could tell if the stator is good or not...it worked okay before i rebuilt the motor?

Also, what wires coming from the stator are actually needed to make the bike start and run...not worried about lights.
What does the pick up coil do? The little do dad that sits on the side of the flywheel and has a red/white wire coming out of it.

Trying to find a used CDI, anyone have one ? If I spend another 300bucks and it doesn't fix it, hard to explain to the wife.
