I just got a 75' 360T that doesn't run and when it does the main fuse blows according to old owner. When i put the key to on the neutral light comes on; all lights work, once i switch it to ignition i loose power to the lights the starter won't turn ( it will when jumped but their is no power to the coils anyways so no start). Also the headlamp is good so that is ruled out already, as are dirty connectors. I know i will have to go through the wiring diagram but if it turns out this is a common issue some help would be great.
Thanks in advance to the genius that may have an answer.

 

My brother had a similar issue on his 1974 CB360. In his case, it turned out that something (a screw driver for the toolkit) was touching the ground wire and shorting everything out. I'm not electrical genius, so maybe I'm describing it sort of wrong. but just check over and see if you have anything touching a wire that shouldn't be.

Good luck the bike! Cb360s (and 350s) are fantastic machines.

OT, here's a photo I took two days ago on a ride on some gravel roads:

 

It turns out to have been something of that sort; i took apart the throttle and both the start button and kill switch were in pieces and the wires were bouncing around inside of it who knows what happened but i am now looking for a replacement setup; and for know just made my own button by crossing the wires... the bike goes great.
