no spark, need help please

[rideblue_06]

I just bought a banshee from one of my buddies. He got in a accident 6 months ago and was killed. Well anyway I bought it from his dad. Before his accident the bike ran fine, never had problems with it. He had rigged up his bike to crank without the key. Well I have the key switch and plugged it in to the white connector with 2 wires. One wire is black and the other is red with black stripe. I can't get any spark and I don't know how he was cranking it. Please give me some suggestions of what I need to check.
