Yeah, I told the shop that I am dropping the truck off to that I think the truck needs to be rewired. My appointment is on Wednesday the 28th.
Just the thought of some "shop" messing with the wiring in my trucks/trailers ties knots in my stomach.
I just about re-read this entire thread and still stick with one of my prior statements.
On most all "modern" electronic controllers, there is a little green indicator light which remains un-lit when no trailer is connected.
Plug a trailer in and that little green light will come on.
Push the brake-pedal and that green light turns red, often followed by a string of red dots; more dots with more brake application.
The ONLY way that controller knows a trailer is connected is via that weak low-voltage passing through the magnets to GROUND.
Whenever a test-light or volt-meter is put to the BRAKE wire, the test light or volt-meter then becomes the path to GROUND and will read that low-voltage signal.
The four or so volts should not be enough to activate the magnets into pulling against the hubs.
Then again, I could be wrong, not because I don't know what I am talking about, but because I am not personally looking at the set-up you are having problems with.
I have said it a million times before, electric brakes are a joke.
