I just bought a new 6x12 enclosed trailer with LED tail lights and I can't keep the Blazer from blowing the 10amp fuse under the hood for the trailer parking/running lights. More specifically, the fuse will blow after having both the brakes pressed and a turn signal on. I drove over 200 miles with just the parking lights on without blowing the fuse but when I stopped and turned on the signal, it pops.

Any ideas? Bad ground connection? Short?

Where is a good place to start?

PS- Here is a pic of the trailer.

 

A short can cause a fuse to pop you might have a short in the trailer plug its self id start checking the wires



know any 1 with a trailer ? try the lights on there trailer see if the fuse blows

fuse might be weak too but id check for shorts 1st

 

Thanks for the reply. Trailer is new. It blew 10 and 15 amp fuse. Where is a good place to start looking for the short?

 

like i said i would try on a different trailer if it dont blow your trailer might be the problem if it dose i start checking the trailer plug on the truck
