I have a 95 fxstsb bad boy with an electrical problem. crank it up all lights work fine after a few minutes headlight blows rest of lights go real bright and bike shuts down everything goes off ater a few seconds lights come back on and can crank bike then does it again is it the voltage regulator or a circuit breaker

Check you running light bulb.. some of those have two elements in them and one side could be blow inside the single bulb. The blinking is how the car tells you that you have a bad bulb, or maybe a short. Mostly likely it just a bulb.

What wiring diagram. There are more than one. You would likley be best to obtain an service manual.

For starters, "..worked fine, for a few minutes." sounds like a current overload issue. Is the headlight wattage greater than the wattage of the bulb(s) you are replacing? If so, you're asking for trouble; the least being burnt wires and circuits. Worst case would be a fire.
Assuming you're within wattage specs and assuming you've checked fuses, it's a matter of using a test light working backwards from the headlight ( if you have power to the headlight but light does not work, you either have a bad bulb or it is not getting "grounded").

sounds like dirty carb get a rekit clean and boil the carb what i mean by boil go to auto store buy strong carb cleaner put the strip carb in it for two days take it out using compressed air we use 300 lbs blow every hole out in that carb if yu see tiny holes take a wire and poke the blow them out again put back to gether with other parts you boiled like the jet and down spout turn adjust ment screw out 4 turns that should get it started the run and adjust from there should run fine main thing dirty carb problem

Usually this is a bad headlight switch. It CAN be caused by extra lighting or a bad ground on a trailer light connection,though. don-ohio

had same problem, its ur headlight switch and can be the electric harness that the headlight switch plugs into. mine is a 98 too.

does the fuse keep blowing ?? it is also on the same line as the cigarette lighter if the fuse is blowing check that there is nothing stuck in the lighter socket that is shorting it out. Could also be a bad ground wire not makeinig contact.

You have a bad electrical cluster. Replace the cluster and your dash lights speedometer and tach should work just fine.

You have a bad mutifunction switch or headlight switch is going bad and is over heating then cooling off comming back on Have a mechanic check it cause there are other things that can cause this. Since it's not blowing a fuse at this time I would say the head light switch is bad.

well your highs werk and you replace the lights and it still dont werk you migt wanna take to a mechanic i had that problem with my 2002 civic just replaced the lights and it werked there is a fuse in under the hood were the fuse box is at check there.
