Maybe someone can help me. I loaned my quad to a friend (1st mistake) He said that he left the key on and the battery went dead. They went to jump it with a battery box and it wouldn't work. I got it home and checked everything out. Put it on a trickle charger and checked it the next day. When I took it off the trickle charger and went to start it, everything went hay-wire. There is a loud clicking noise from what looks to be an ignition relay. I checked all of the fuses and everything looks ok, but this thing still will not fire up. Could they have cooked something using a jump box? I was hoping not to have to take it to a shop to have it fixed. Any ideas to test this and see if I can run down the problem and fix it at home?
