trying to get a cb350 running, no key, 1972. Took off the ig switch, see 4 wires, brown, red black, and (I think) a brown with a stripe. Regardless, which ones do I short to see if I can get spark? amazingly the lights work. When I short out the red/blk, headlamp comes on. short out br blk, tail light comes on. At least thats the way I remember it. But when i try all combos, the push switch on the bar for the starter wont crank it But if I short the starter solenoid, the starter cranks, so I know that circuit is ok.
