Are you trying to get rid of the break away?

Smitty you should probaly keep the break away.Arent you in to rc cars if so just use a 3 cell lipo for your battery just unhook the truck charging system from the battery.It will last a year without charging. The battery is just along for the ride unless needed.If you choose not to use it. Hook the break away cable to the truck for looks only if you get caught with out it the fine is 200.00 dollars

I can't adjust the brake gain, I figured it had something to do with the battery?

Test it. You can buy a whole new break away system on Amazon for under $70.

I lost my trailer brakes this weekend and did some testing tonight.
The breakaway on my system has NOTHING to do with the trailer brakes working or not.
Its really a secondary system ontop of the trailer brakes to automatically apply brakes if the cable is pulled.

So long to short... YES, you an cut the 3 wires. But like said, it's required by law.

FYI, My issue is a one of those stupid splices under the trailer shorting out.

You mean with the brake controller inside your truck?

Do this first. Jack up your trailer tire and give it a spin. Then have someone engage the trailer brakes with the brake controller. If you have a tire that doesn't stop spinning then start with that one.

Make sure you're getting power to the magnet inside each drum. You can check that with a volt meter. You will need to have someone engage the trailer brakes with the brake controller to check it.


If you have power at the magnet then you can test the magnets. Again, have someone engage the trailer brakes with the brake controller. You can then put a big screw driver, wrench, or big pair of pliers on the magnet and it should hold it on there. If it won't then replace the magnet. They like to go bad pretty regularly.

X2… mine stopped working this weekend as well… second time. First time the wires were pinched and one was cut. Will have to check it out today to find out the new reason

Remember to ck your grounds on the trailer no ground no brakes.If you put 12 volts to the blue wire and a ground all your brakes should lock up.
