trailer light module issues

[Brad[_2_]]

I have an Avionic trailer that has been revised to run a flat-4 plug. My Kia Sportage requires a light module kit that plugs into the wire harness and then outputs to the trailer plug.

I keep blowing up the modules..............any ideas what might be the cause? These things are expensive and usually I need to install a new one at the start of each season.

thanks,
Brad

Unlikely your problem...

I had a boat trailer that blew fuses on long trips but everything checked out fine when the mechanic checked the wires.

The problem turned out to be a tail light wire shorted to the trailer chassis. The trailer had to be connected to the hitch to cause a problem.

I found exactly the same problem with my previous Cobra that Alan describes.
It behaved fine until connected to the car.
The car suggests using a 30A fuse for the trailer circuit, likely for electric brakes. For just lighting, 10 is more appropriate and will save the module.

- Cleaning all exposed, and rusty, trailer side contacts helped in my case, also try getting a flat 4 plug fused contact. Fuse is located right inside of the plug. Ever since I replaced all lighting with corresponding LEDs permanently "fixed" the problem.

Also, check the resistance with the multimeter between the positive cable and the ground, maybe one of the 4 legs is exposed and leaking voltage pulling extra amps. You could also connect your multimeter in series with the positive, turn on your lights, and check the amperage consumption. Good luck.
