Mine just went out today and it was not the 10amp fuse. Did not have time to find which safety switch is failing, but if you pull the white plug from the starter relay, (open the engine bay, it's mounted on the same side as the key switch on the frame of the panel, easy to get at) and jumper a wire between the two large wires (Red and Red/Yellow), then turn the key to start you basically bypassed all safety switches that prevent the relay from engaging and are letting the key to provide power to the starter solenoid. My seat switch is already jumpered out. Until I can locate the darn switches, then figure out which one is bad, find the part number to replace, and wait for it to arrive, I'll keep the piece of wire wrapped around my throttle to use and the relay unplugged for easy access.
If anyone has the part number for these switches, please post them.
