I set the gain to 10.0 on the brake controller but that doesn't lock up the trailer brakes. It seems to just barely apply brakes. Tried moving the manual handle all the way left when moving and that does not lock the trailer wheels either.
I brought the truck and trailer to 2 trailer shops. Both shops put the trailer on a tester and were able to lock the wheels. They said the trailer was working fine.
They put the tester on the truck and the most it read was 5 volts. One shop said it should read 10 volts when the gain is maxed out.
The truck is set to "Light Electric". Wondering if "Heavy Electric" would help. If so, I haven't been able to figure out how to select "Heavy Electric" on the brake controller.
Any ideas?
