Brake controler

[Dozer]

I finaly got my brakes put on my wheel house today. Tested them in the shop with the battery charger since I cant fit both the house and truck in at the same time, everything seems to work. Hook up the truck and pull it outside and no trailer brakes. Light on the controler is green, telling me the trailer is hooked up. When you manually put on the trailer brakes the light should change from green to yellow to red which it doesn't, it barley changes colors. After dinking around with it in the yard for an hour I cant feel my hands anymore I unhook the truck and bring it in the shop. At the back of the truck I have 1.7v with the brakes off and 4.5v with the brake controler maxed out. Is my brake controler junk? Under max application of the brakes I should have a full 12v there shouldnt I?

Im going to dig my other trailer out of the snowbank tomorrow and see if the system works on that trailer.

If my controler is junk what do you guys recomend I replace it with?

Tekonsha ....! And, you should not have any voltage unless you are applying the brakes, and full voltage when fully applied, provided the controller is turned up all the way.

Check your connector for corrosion, verify the settings on the controller and double check the readings.

If they are the same the controller may be bad, ( if it is on the max setting) but more times than not its corrosion this time of year.

Had time to do more testing this morning. Constant 1.7v output with 4.7v with max brake applied right at the back of the controler.

New Tekonsha Primus IQ controler will be here on monday.
