So I am trying to start 78 cb750f for the first time in 4 years and I change the fluids, change the plugs, and connect the battery........and nothing. No headlight, and no turn signals. I change the ignition switch because it was cracked and we figured that was the problem, and now we have turn signals, but no headlight, and not turning over. We also checked the starter solenoid(spelling??) and that was not it. We checked the current to the fuses and all of the wire harnesses and that doesn't seem to be the problem.
Any advice???
