Hello. I purchased the DayMaker lights for both the main and auxiliary lights for my 2013 Road King Classic. I am having the strangest issue with the install. The right auxiliary will not turn on. Thought is was a faulty light so i switched left/right and have the same issue. The main and left auxiliary work fine. If i plug back in the original auxiliary light on the right, it lights up no problem. Any ideas? Thanks

 

Do you have a 12volt test light? Check for power at the lamp plug , on my 2013 SG it's + wire is grey/black. If you have power then check the ground wire , put the clip of the test light on a 12volt sources, like the positive battery terminal and anything the tip of the test light touches will show you ground. Check the lamp plug black wire to check for ground. One of the two wires is not working or has a loose connection. Then trace the bad wire back through the harness

 

thanks bsritch. I will give that a try.
