I'm having an electrical problem on my 1974 CB750k and it wont start.

After parking the bike in the garage at my office, then returning to it in the evening, the neutral light (and headlamp) would not light up at all. The kick start failed to start the bike as well.

After hooking the battery up to a car's battery via jumper cables, the neutral light came on, but the battery does not seem to charge. While revving the car's engine, I can get enough juice to try and turn over the bike, but it doesnt seem to be enough to fire, or maybe not enough to spark...

After disconnecting the battery from the jumpers, the neutral light will no longer light up at all...

I've checked the main fuse, as well as the other 2, and they are all intact.
I'll replace the battery today on my lunch break, but I've been told by 2 mechanic friends that that wont solve the problem.


Any ideas?
