Electric brakes on a Gooseneck

lenray · Mar 23, 2013

I have a 3 axle Gooseneck trailer and have brakes on the front two axles. The rear axle was removed and reworked and reinstalled, but the brakes don't work. Can a guy get the wires miss matched--the hot and the ground or doesn't it matter---any ideas
Thank you

doesn't matter. Check for good gound

Does not matter. Check for power first, then listen, if you have power you can hear the magnets hum. If you get just a little brake first check that they are adjusted. They have to be almost dragging a little. If that's all good then make sure they are on the right side, the are rights and lefts and I've seen more than a few on the wrong side. After that it's time to pull a hub and see what's wrong.

If you are asking about the 2 wires on the electro-magnet, it doesn't matter. There is no power and ground. The electro-magnet is an insulated coil and does not come in contact with the ground of the trailer. So polarity there is not important.

You can connect a battery or charger to the two wires of the brake coil, put a screwdriver in front of the electro-magnet, and you can feel the electro-magnet. It will magnetize your screw driver too.

The back brakes on my 2 axle trailer stopped working. Something had cut one of the wires feeding the back axle.

Get a volt meter and find where the voltage is missing. Try this, pull the safety cable and see if the battery will energize the coils.
