I have a Chevy Silverado 2500 HD 2007 classic. Alsi I have a homemade
trailer with electric brakes.
I wired in my Journeyman brake controller. Plugged it using my
vehicle's standard plug, and also used the proper fuse to fuse the "RV
power supply" wire.
The good news is that the controller seems to send power to
brakes. Also the power on the auxiliary line is on.
What surprises me (or maybe is bad news) is that even when the brakes
are not in operation, I measure about 5 volts on the brake terminal
inside my trailer's electrical box. Applying the brake control
using a manual lever increases this voltage (as evidenced by the brake
LEDs) to full voltage.
My question is WTF? Why would there be any voltage on the brake
terminal when the controller is not activated? Is something wrong?
I will try to call Journeyman on Monday, but any ideas will be
My second question is that the power to the RV plug continues even
when the engine is turned OFF. That seems to have a nice potential to
drain the battery. The obvious remedy is to pull the trailer plug
every time it is turned off, but that seems dangerous. Is that normal?
