I have a 02 Big Bear 400 4x4 I changed the battery, starter solenoid, coil pack, and spark plug. And its still not firing off. But when i was installing a light bar i nipped a red wire and two white wires and there was a spark at the battery and will not crank after fixing wires. Was running perfect before wires were cut. Any ideas on what to check next would be appreciated and thanks in advance. I am fairly new to working on bikes.
