I have a 02 TRX350FM Rancher. My problems are with the lights being dim and the electric start (and cooling fan too). The lights work but are always dim when on and the starter works but I already went through a battery after about a week and a half (then it just died). I'm thinking it's the regulator, and hoping it's not the stator.. I was told about a three way diode in the fuse box, does this have any significance? All the fuses look okay, haven't changed the wire harness since it was purchased. I just replaced my brush kit. And also I don't think the fan runs after the motor gets hot. I'm going to put a new battery on tomorrow and see how long it lasts, if it dies again, I think I will try a new regulator.
I was wondering if anyone has any tips for me.
Thanks for any help.
PS: I live in Alaska, I run it in cold weather.
It is an awesome machine, I would just like to fix the electrical problem.
