I have 2 scrambler 500s both 2000 year. Went trail riding & they both ran hot at the same time. Neither fan was working. They must be twins! Checked one by putting 12 volts directly to it, nothing. Haven't checked the other one yet. The only ones I can find are around $225 each. My question: do they have to be scrambler specific? Shouldn't they all be about the same, aside from maybe modifying the mounting bracket? I don't wanna sink 500 bucks into these old hoopties if I don't have to. Thanks for any info!
