Have had problems with fan not kicking on. It is not locked up. The previous owner placed an aftermarket auto ignition switch on the atv (acc, on, off, start). Sooo- I anticipate that the two extra wires not hooked up to the switch complete the loop. How can I wire the switch correctly or wire a manual switch between the positive source and fan? The colors of the fan wires are brown and orange. The colors of the wires that are not hooked up to the ignition switch are brown and black. The Scrambler is a 4x4 1999 400. Please help as I suck at electronics!!!!!
