umberto:
You're welcome. I hope it fires right up for you.
drewwilhelm:
Well guys.... still no spark. don't really know where to turn here. Im going to try and test all electrics again tomorrow and see if i can find the problem, but I am pretty sure I have checked them all.
umberto:
Man that's frustrating! If it were me, I would start at the stator and flywheel and work your way all the way through the electronics to the kill switch. Check and make sure every connector is in good shape and seating properly, every component registers the Ohm measurement it should, your grounds are clean and paint fee, and that the wiring harness is free of frayed or cut wires. You might also try disconnecting the kill switch as it can have issues and not allow spark.
drewwilhelm:
OK, grounds are solid, no frayed wires still no spark. Im wondering if it is my regulator but I don't know how to test it. I tested the coil its fine, but Im not sure how to test everything else is there anyone who can explain this the most simple way possible.
Oblivious Maximus:
My 87" 250 lost spark at home (thankfully) after a long trail ride. I used the link Umberto posted above to Sandblasters tutorial. The stator test seemed erratic and i thought i was doing something wrong but after several tries the white/red to black/yellow numbers were inconsistent but just slightly out of spec on the low side.
I was lucky to find a used stator on ebay on the first search and it fixed the spark problem as well as hard warm starts.
