I have a 2006 Arctic Cat 90 utility. There is a plate with 2 resistors on it. The larger resistor gets very hot. I recently bought the 4 wheeler for my grandkids, and don't feel comfortable with it. The part number is 3303-142. Before I order a replacement from Partzilla( ships in 55-60 days), could someone explain what it does and why it may be getting so hot?
