Your voltage regulator is not working properly. You may have to convert to a more modern style regulator. Get a voltmeter and measure voltage at the battery with bike off, should be 12 to 12 1/2 volts. Then measure voltage with bike at idle and then at high RPM, should never go over 14 and 1/2 volts. Also bad connections, dirty, rusty, loose etc will cause the gen to work harder and put out high amps. Make sure you have good clean connectors at the battery posts also. GOOD LUCK.

Harley troubleshooting

You have a short in that circuit, check for loose or bared wires in the headlight or blinkers or disconnect any plug. Leading to those parts one at a time until the fuse stops blowing then trace those wires to the problem

sounds like a shorted out wire connection but could possibly be something else in the electrical circuit causing the problem.Check for loose connections or a break in the insulation rubbing onto another wire or metal surface.

Why my headlight fuse keeps blowing out on my 2001 sportster. i have a brand new regulator. what else should i try?

Regulator should not affect headlight fuse blowing. You could do a voltage drop test otherwise look for a short circuit in the headlight wiring. IS it shorting and blowing the fuse on both low and high beam? Look for chaffed, broken wireing insulation on wires in headlight assembly and wherever the wires might be crushed by steering stops or mighth be rubbed through from vibration etc.

Lights keep blowing the fuse

You can pull the light apart and check the amperage they require since they are not the factory headlights they most likely have a higher amp requirement and find out what that is and then install the proper required fuse for them. Also be sure to check and see if the wires are properly hooked up and wrapped properly and are not grounding out on any metal or other wires. This should solve your problems. Might also want to see if the headlight relay is also the proper one to cover the amps they require as well. Hope this works for u and good luck

Accessory fuse keeps blowing, headlight not working

I know this sounds aomewhat general, however please give the following some thought:
Check your relays, if you have an aftermarket horn you may have a different relay. To troubleshoot unplug your headlight, unplug your horn, etc.. Turn your ignition switch to accessory only. See if the fuse pops. If it does unplug whatever added accessories you may have still have plugged in. Once you can get the fuse to stop popping, turn the ignition switch to on. Then one at a time plug you accessory, headlight, etc. back in. When you find what pops the fuse, unplug that item, start plugging in the other items, if the fuse has not popped you have potentially isolated the circuit causing the issue. Now check the wiring for loose connections, bad ground, and CHECK the relay if that item has one. Hope this helps,
