I called my dealer and mentioned the coil and he said it is most likely a bad stator. What is a stator, where is it, what does it do, why did it break, and how much is this gonna cost me ??? Taking it to the dealer since I am not a mechanic, just curious what to expect. Thanks in advance for any info.

 

A stator is your machine's the equivalent of an alternator. Its located behind your fan. They usually go after exposure to water.

Raptorlegs is correct. This weird looking set of coils is installed behind the flywheel and creates electrical energy to create "the spark", and its also used to created electrical energy to charge the battery. To view its different coils, surf: http://community.webshots.com/photo/...73581411YdAizB

Unforetunately, stator assemblies are very expensive. Much higher cost then a $3.00 Spark Plug. GGGRRRR!!!! If the dealer's price is "too much", you may want to contact some of the Performance Upgrade Dealers on this forum. They often remove working stator assemblies and replace with PVL Ignition systems. These more expensive PVL Ignition systems are often used by racers. Thus, these folks might have a used stator assembly for 1/2 -> 3/4 price (???). If wondering, I obtained my "used stator" from Billy Holt @ WRH Racing. Email: "billy.holt @ wrhracing.com". If you are a mechanic, installing a used stator youself will save you tons of repair dollars.

If wondering, stator coils blow because of:
A - bad connection in the electrical system and the electrical energy revers spikes into the stator coils.
B - stator is covered with mud and over time, this insulation layer traps too much heat. Thus, "over cooks" the stator coils.
C - Swamp mud & crud eats away at the external covering of the stator coil wires. Thus, shorting out the coils.
Note: Many say the main reasons stator coils blow is because of bad electrical connections and thus, spikes & brown outs in the electrical system flow backwards into the stator coil(s). To me, I think it's a combination of all 3 reasons. To reduce electrical spikes, add dielectric grease (12V automotive wiring grease) to every wire connection, plug, socket once a year or even twice a year (if you love driving through mud / crud conditions).


As a suggestion, install a better ground from the battery to the frame. I've been told this extra ground helps reduce electrical current flow problems. Not too sure if it really does work, but it's worth a try. For a picture, surf: http://community.webshots.com/photo/...89612822mtEmFB


Hope this helps....

The spark is generated by two of the coils on the stator. Neither have the copper windings exposed.
