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,

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.
