replace the faulty fan relay or check for a problem wire from the ignition to the sensor to the relay

Polaris fuel filters are usually in the fuel line coming from the valve that turns fuel off. This model does not seem to have an inline filter, however you can always buy a universal one and splice it into the line so that then it does have one

its more than likely under the seat...

Start at a turn and a half out.

Have you checked the fuse terminals coming off the battery there is a fuse some times it is a bad ground make sure battery is charged

charge system fault
could be the charger ( alternator) voltage regulator or loose wires
indicates not enough power to run the ignition system when the head light is turned on

Have the ignition module unit tested, I had one go bad and it did the same thing. Eric

If I remember right it does the little black box (not the CDI box) the 330 I replaced the control box on once i replaced the box the speedo did light up again been along time ago but I think if you repalce the control box it will fix your problem
