Tried to go riding yesterday and when I got to the mtn. 145 miles 1 way. I started my sled and it idled fine when I hit the throttle all it did was blubber and sound like it fouled plugs. After changing 3 sets of plugs I noticed that I had no electrical. No tach, headlight, tailight no beep beep when started no backup alarm although it does go into reverse, no hand or thumbwarmers. I looked at the fuses and they appeared good and looked for any unplugged connectors. Took the DPS key off and on several times to no avail. What could be the problem????????????????????
