On a 2013 fls I have installed a custom dynamics led light strip that replaces my running brake and turn signals. After three seasons all functions on the unit have stopped working, zero illumination. I have checked the connections and all look and feel solid. Any thoughts?

 

VOM...check the connection to the rear under the seat for voltage making sure it's between the feeds and the return ground, not the frame. What do you have? Nada? Then it's in front of it and now it gets interesting.

 

check the output with a voltage meter, or another light that you know works like your old blinker or something.

 

wrong thread

 

I am unfamiliar with that component...Your post seems to suggest it's a plug & play replacement for OEM...

If so, obviously first check for a blown fuse, then that the connector has good contacts, then finally separate the connector and see if power is getting to the OEM side connector... as mentioned, that will tell you in which direction to look for the problem..

Power to the OEM connector... call Custom Dynamics. They are great at walking you through trouble shooting their components.

If no power to the OEM connector, the Custom Dynamics component is probably OK, but you have an issue between the battery and that connector... time to get patient and systematic as you investigate for the problem...

Good luck with the diagnostic testing and repairs...
