Hi I'm Jacob. I have been working on motorcycles, for a while now. I've got a 80 xs400 that won't start. Used a circuit tester and pumped 12v into battery connections. Lights come on, but bike will not run, unless I put 12v to the coil hot wires. I'm thinking its the igniter box under the battery housing, but I honestly don't know for sure. Does anyone know what it could be that is causing this problem?
