Yesterday i was riding down the road on my vulcan and the bike just shuts off. no bucking, not like it was starving for fuel. The running lights and engine lights were on still so i was not without total power.

i did get it restarted and brought it home. A few weeks ago when i went to start it i had no power. i thought it was battery but it made no sense. i jiggled some wires and then i got to start.

i woudl think it is an electrical short not a battery issue but i need help. ???? where do i look?

I doubt its a short. That would most likely cause something to burn up, or a fuse to blow. It may be a poor connection. Often times when you have this type of problem it can be traced to a poor ground although it is entirely possible for some other connection to become intermitant. Bikes are subjected to plenty of vibration. If you recall just where you wriggled the wires to get it to work, start looking for it there.

turn it toward a wall at night and turn on the key then jiggle the key.see if lights flash off and on.i have had 2 ignition switches do this on hondas.

The ignition switch idea ia a good one, as is the GROUND issue. Also the plug on the ignition could be loose. CB750 hondas are notorious of this. Check for loose wires under the gas tank that go to the coils. basically any wires that look loose, bad or a indication they have been hotter than they should have been.

Good Luck
