12' owens open 5k trailer with brakes.

-DO NOT HAVE THE AUXILIARY BATTERY INSTALLED

- last weekend i converted the trailer harness truck side from 7 round to flat. the old harness had two wires not connected. i voltage checked and hooked up the tail, turns and brakes. i tested it that day and all the light functions worked including brake lights. i did not however try driving it. well today when starting work. i plugged them in and the thing wont move. unplug the trailer and it moves fine.

so forum, does it seem like its a trailer,brake controller issue, or wiring issue?

really need this fixed up,id rather not pay someone else to fix it.

thanks,
-Juan
