fz07nc Posted August 3, 2015 Share Posted August 3, 2015 So today I was set to upgrade my headlight to the 3800 lumens Cyclops H4 LED bulb, but I encountered a couple hiccups. Upon testing operation of the headlight, I found that it was not turning on. I reinstalled my original bulb and that did not turn on either. Since I do a lot of daytime riding, I'm thinking that my headlight has been out for some time now. I checked the 15A headlight fuse at the box and it looked fine. Has anyone else encountered this? I will add that the lower light in the headlight housing is working, but the larger, main light is not. A few weeks ago I did lowside and break off part of the headlight switch that allows you to change between high and low beams. Could this be my problem? The switch only appeared to be broken at the physical portion that your left thumb contacts. Other electrical modifications are an LED Blinker genie to have my front turn signals operate as daytime running lights. I also have the EJK controller from Dobeck. Thanks in advance.

Global Moderator sorkyah Posted August 3, 2015 Global Moderator Share Posted August 3, 2015 I would double check the fuse for an open. If you have an ohm meter, the resistance should be about .20 ohms or OL then remove the headlamp switch to check for open/broken contacts ATGATT... ATTATT, two acronyms I live by.

cndnmax Posted August 3, 2015 Share Posted August 3, 2015 Is the bike running when your checking the headlight operation? Link to comment Share on other sites More sharing options...
Premium Member noltz Posted August 3, 2015 Premium Member Share Posted August 3, 2015 I had this happen to me from the dealership, they broke the headlight switch and neither does the low beam or high beam turn on, they had to order a new control assembly to fix the issue, it was around 70 bucks.

fz07nc Posted August 3, 2015 Author Share Posted August 3, 2015 Thanks for the quick replies. I'll check the fuse for an open. I have a multi-meter I can use to check resistance/continuity. My bike was running at the time of testing. Thanks for the note noltz. I suspect that the switch is broken. Can you confirm that the bulb in the lower portion of the headlight housing was working when your low and high beams would not turn on? Did they need to order the left handlebar switch?[/img] Link to comment Share on other sites More sharing options...

fz07nc Posted August 5, 2015 Author Share Posted August 5, 2015 I have this switch on order. Crossing my fingers that you're right noltz Either way, I needed a new switch because the rocker portion broke off of mine. Link to comment Share on other sites More sharing options...
fz07nc Posted August 13, 2015 Author Share Posted August 13, 2015 New left handlebar switch installed and still no headlight... I have not tested the relay yet; that's my next step. Link to comment Share on other sites More sharing options...
fz07nc Posted August 15, 2015 Author Share Posted August 15, 2015 I'm not sure what happened since installing the new left handlebar switch and now, but my new headlight is working. I've notice that this new one does not come on with key on, engine NOT running. Link to comment Share on other sites More sharing options...
