Have you checked and cleaned the bullet connectors for the running light wire near/in your tail section and indicator lights in the headlight bucket? If they come on and off intermittently you could have a loose connection, or you might have a break in your wire insulation that's grounding out on the frame somewhere. Also check to make sure these items are properly grounded. Look at a wiring diagram to get familiar with where your power should be coming from, then chase down the problem. A 12 volt test light and a multimeter will really come in handy here. They are cheap tools you will surely use over and over! By the way, not knowing what bike you have, I can only guess, but I think the fuses are usually 7, 7, and 15 amps. Have you been blowing then 5 amp fuses, or are you just replacing them as preventive maintenance?
