Was riding last night and suddenly all my electrical cut out. The guy i was riding with it noticed my headlight and signals were out and pulled over. My throttle was also completely useless. It would bump start but cut out after a few putputs. Had to leave my bike in a strangers garage and ride bitch back home...
I've been riding the bike since march with no problems at all.

Any ideas on what could have happened? What should i check?
 
Start by checking all the fuses even the main.
If I had to stab in the dark (no pun intended) check the tail light / Turn sig wiring at the rear fender seat area. Very common to get pinched and short out.
 
total noob fix. when i checked the fuses on the side of the road they didnt look blown. turns out the main blew on the ends or something. when i swapped it out everything worked fine...

Ahhhh. But now the rub, and the eternal question that sould be in the back of your mind every time you ride... WHY did it blow? ::)
 
trying to figure that out as well. a guy i ride with suspected it might have just been an old fuse. Because it wasn't even blown, the ends were just worn out and falling apart. makes sense considering theyre probably the original ones from the 70s
 
Wasn't an old fuse. Went through 3 brand new fuses in 10 minutes on my way home the other day....
After the third one blew I noticed my brake light cable was pinched between the seat pan and the frame.. so i moved that to a safer position and had no problems at all on the way home. That couldn't have been the problem could it? I don't feel safe riding the bike for long rides, what should i do to make sure i fixed the problem?
