I have a fe570 running a Timbersled Mountainhorse kit. Long story short I had an issue last week. Starter would not disengage , relay got hot and fried, smoke poured out etc. Managed to ride out by jumping across to battery to start bike. Replaced the relay and now bike won't start. I've swapped the start switch from another 570 and its relay both work fine on other bike. Just checked wiring harness to start switch and no power coming to switch, there is on the other bike. I can't find any decent wiring diagrams and am admittably not a good electrician . Any insides?
