Electric brakeissue
I have a 2005 5 Springdale 28' travel trailer that i recently installed new backing plates on all 4 wheels. when i tried the controller manually nothing happened so i just ended up using truck brakes...

Thanks for the more information. Many of the newer trucks have independent fuses for trailer towing. I would definitely look at the fuses before removing the plug.
As far as replacing the plug that's a good idea if the original looks damaged or corroded. But I would first remove just the brake wire and the trailers battery charge wire from the plug. Then use an extra 15 amp fuse and connect the fuse between the two wires to apply the trailer brakes. Does the fuse immediately blow or do the brakes apply or does nothing happen? It's a quick test that will tell you if you have a wiring short or if the power is even getting to the brakes.
If you have a compass you can have a helper apply the manual override on the brake controller while you hold the compass near each wheel. If the brake magnets are energized the compass needle should swing to point at that wheel.
why wouldn't you just pull the breakaway pin? that will tell you the same thing, the only thing it doesn't test is the pig tail, and it lets you measure the amperage at each tire with a clamp on dc amp meter so you can tell if each magnet is working.
the way to do it first is just use a Ohm meter and measure from the plugin from the ground to the brake pin, if you have 4 brakes then for most setups if everything is good you should get just under 1 Ohm like 0.8 Ohms. this will confirm all your magnets, grounds and the rest of the wirings is good.
if your like me when I was checking it yesterday and got 1.2 Ohm then you pull the breakaway and move on to each individual brake.
