trailer lghts not working

Post by steve06wing » Sun Aug 12, 2018 4:02 pm



No trailer lights when plugged into gl1800. If i hook the trailer up to a power source all lights work. I checked all the fuses on bike there all ok.
What do i start looking at next? Forgot to say trailer lights worked 2 weeks ago when i used it. Thanks for any help in advanced

Is the trailer hitched to the bike? Some need to be hitched for a good ground.

Accidental short while wiring the trailer wires.

Fuse was weak & ready to go. Any extra load, it's a gonner.
SUGGESTION: IF you don't have a Amp meter... put a 25 Amp fuse in it and test it. If the 25 blows, you're near or at that circuits load limit.

This is the reason for trailer wiring isolators. With one of them, you draw power for your trailer lights directly from the battery and only signal through your bikes wiring and fuses. You can get one here:

Harbor Freight has a nice little tool for testing current draw: circuit tester - you remove the fuse in question (up to 30A) and plug this tool into the fuse block, then place the just-removed fuse into the tool (to protect the circuit). It will show how much current is flowing in the circuit...

I have several electrical meters & testers.
My post was for those who don't have said equipment and how to check the system in a minimalistic manor.

...and my post was a suggestion for anybody reading this, including the OP, for a reasonably priced, easy to use, tool - I figured you would already have a shop full of tools! :D

when I saw that tool, I took it home, right then..
