I picked up a 2010 FX450 for a great deal this winter. I decided to get it ready for spring, checked the valves, oil change etc. I disconnected the positive cable from the battery while I had the bike apart. After the service I reconnected the cable and tried to start the bike. The relay clicked but nothing from the starter. Battery read 12.6 volts, checked continuity from the battery to relay to starter, all is good. I then tried to jump the relay to see if the starter would fire. I bridged across the two terminal and got some sparks. Now when I hit the start button I get nothing? Checked all the fuses and none are blown. Swapped out the relay for one from a friends bike, still get nothing when I hit the button. I had a good look through all the wiring to see if something was grounding to the frame but found nothing. I'm stumped. Is it possible that the ecu got damaged by jumping the relay?
