2005 Yamaha Vector wont start FIXED!!!

[kalisto2k1]

Hello,

I have a 2005 Vector er carb model with 3,000 miles on it. I owned it since new. This season the stator went on it, open circuit on one of the 3 loops. wasn't charging but still ran good on a full battery. I purchased a new stator and pickup coil combo from rmstator.com. Tore the sled apart and installed the new stator and pickup coil.

The snowmobile started with some persistence but it did run, idled smooth but occasionally died you would have to babysit the throttle. Also took about 3 seconds of cranking to fire it up. Took it for a ride and seemed to run good, parked it in the driveway and it idled down and shut off. now it wont start again, tried cranking, pulled the plugs and they are wet so its getting fuel, but spark is weak-non existent.

I pulled the plugs and coil out and grounded them, when you first begin to crank, the plugs receive only 1 faint weak spark, after that no spark at all if you keep on cranking. I tested the new stator with a ohm meter on the 3 prong gray clip and the circuits had .2-.3 ohm resistance on them. I also tested the pick up coil resistance on the 2 prong clip and it came back at around 190 ohms. Rmstator lists 185 + or - 20% so that seems within spec. I am running out of ideas of what could be wrong. ran good before I changed out the stator and pickup coil.

I had cleaned the carb earlier this season, ran great after.
I had changed the spark plugs when I put in the new stator with factory Cr8e, I have also tried the old plugs and still no spark.

Thanks
Mike

fixed the sled!!! it was the brand new pick up coil. Ohms tested fine but output voltage was no good. When testing pulsar coil get multimeter with max voltage. voltage should be 7-12v while cranking 300rpm or so, my pulsar coil was .7-1.3v. Coil was brand new but defective. I just cut the end off and fed my old pulsar coil through stator loom and reconnected.

I have the same issue on my 2008 Vector LTX but i get .5ohm on the stator wires and 150Ohm on the pickup coil. I guess you had to pull the engine out to get to it? I bought a new Pulsar/pickup coil from RMstator my try that and see if it cures my issue.

How did you adjust the gap between the flywheel and Pickup coil? I just installed one in mine and not getting any voltage reading. Maybe I got a bad coil too.
