Trailer Brakes Shorting Out - Controller shows overload

I had the low vtage thing on my 10 year trailor, i didnt have the option of another tow vehicle. So consider yourself ahead of the game. I changed and redid all the grounds, re-did all the connections. I eventually had to rewire. Do that first, not that hard. I wasted a few days troubleshooting and not doing. After you check the grounds. That is unless your good woth a meter, bit then the problem cluld be while your rolling and may not be a problem while its sitting. And dont forget the e break switch eaither.
