I have a 2000 FLHTCUI and I added the Harley headlamp flasher unit to my system for that added daylight visibility. Ever since then I have been having Harley Davidson headlight problems with the fuse. I have been blowing them about every 2 -4 weeks of use if I have the spots on. When I leave the spots off there is not a problem. I have thought about putting a 20 amp fuse on to see if that will take care of it but I worry that I could have a more serious problem develop because of that. The interesting part is that the fuse has only blown when it is dark out and not during the day. I have also added turn signal accents that mount to the fairing but I have not had a problem with those. What else can I check? Thank you, Virgil
Virgil, Was this Harley Davidson headlight flasher unit designed for your make and model bike? Was it plug and play? There should be specifications in the instructions that will tell you how much this flasher will draw. You either have a dead short, or you are over loading this 15 amp fuse. Check your headlight plug. Verify that your connections are secure and that the plug has not melted. If you are overloading the circuit, you need to feed the headlight from another fuse that is not as “full”. Or, if you are knowledgeable of DC voltage, you can find the correct feed wire and isolate it with it’s own fuse.

Where is my turn signal flasher on my 2013 road glide
Hi Richard. You have a turn signal module.
It’s behind your right side cover, behind your ABS and behind your Oxygen sensor plugs.

Headlight flashers are illegal in most states…
On the headlight flasher unit,he needs to make sure the connection is good and that he has put dielectric grease on the connection.It may be that resistance has build up in the connection,and it isn’t at it’s best which will cause the fuse to blow and or the connection to melt.I know this because I had this happen to me on my ’97’ sporty.
Virgil,
Before you discard the fuse, look at it closely to see if it’s blown (silver dot exploded) or if the element is crystalline looking and “melted apart”. Silver dot
indicates sudden amperage surge, such as an iltermittent short to ground.
Melted indicates slightly excessive amperage draw such as from too many loads on a circuit.
Hope that helps, Eric
Leave your headlight alone and change your spotlights to led amber. You can get them amber on/white off if you want. Much better for daylight vis and almost no electrical draw. As bright as white ones at night too and all legal

Joe,
Turn your handlebars hard right.
You will see the turn signal module in the neck area behind the left side nacelle. The module is grey & rectangular.

I have a softail where the headlight and normal light all of a sudden got switched. I have to switch on the headlight to have normal light. Also the right position light indicator on the dashboard died. Left still working. All position lights working. Any ideas, relay problems?
Hello Tony!
Could we get the year of your softail please?
Thank you!

Tony,
If the high beam & low beam functions are reversed, either someone wired the headlight plug incorrectly or the headlight plug may be damaged.
As far as the right side indicator light goes; you will have to lift your dash and inspect the indicator’s bulb, socket, & wiring. Use a test light or multimeter.

Have to give you a great thanks for replying. This is the weird part. I rebuilt the bike totally but regarding electrics I only changed to Kellerman 3-1 lights and a small headlight last year.Drove with it the whole season and all worked fine, in the end something just happened and hedlight normall light was swapped as well as this right indicator light on the dash stopped. Been testing and swapping fuses, checking the relay. Ringing with multimeter and checking all grounding all in order so was suspecting a relay or a switch broken that could cause this behavior but no success. Perhaps grounding issue. Troubleshooting continues, if you have any other ideas popping up please let me know.
