tempte trailer lighting issue

sounds like a ground issue,could be the pigtail or the receptacle on the trailer. open them up,look for the green crusties. probably need to cut and reinsert the wire ends on the receptacle. then pack it with grease.

 

LED lights are more sensitive to low voltage & bad grounds then incandescent lights. Though it seems that there is a ground problem. Check the ground stud at the seven way light box. If it's a newer trailer follow the harnesses for the problem lights. These days they break up the wire cables into replaceable lengths and they tend to have bad contact at the plugs

 

With the blinking with the turn signal you can bet it is a ground issue. Probably not some fancy circuit board to replace but may be hard to find. Did you check at the plug on the inside of the front of the trailer, crawl up under that front hopper bottom and wiggle. That has caused us some issues with an older timpte. It can be hard to keep that plug firmly connected.

 

Also I assume that it did not get better just by driving it a while. It is super common for us to have weak ground when first hooking up to timpte. All or many lights blink with turn signal ext. then we drive it a little and it is fine. Don't know if it starts grounding through the hitch better or what?
