I could use some advice. My 2004 1M Mountain Cat 600 is losing power to the headlight and taillight when the handlebar warmer switch is placed in the low position. When the switch is in the off position or high position, the lights work properly. When in low however, they have just a little bit of light showing in the bulbs and are not working properly. I've checked the ground by the recoil starter and replaced the handlebar warmer switch to no avail. Anyone have any suggestions? Thanks.
