Trailer Wiring

[Donald Watson]

Curt,

You had me wondering about the brake
controller. That’s why in a previous post I asked you:

”I’ve probably missed previous posts
on trailer brake controllers, but it sounds as though you are using new
technology I am not familiar with to supply the variable DC brake voltage.
What are you using for a brake controller?”

I didn’t ask my question well enough.
Greg, however, asked the question properly. If I had followed up on the Tekonsha
info you gave me, I might have realized that there was nothing really ‘new’
about the control voltage the controller was producing. Good thing we have
lots of proof-readers and competent minds to guide us at times.

Re: Trailer Wiring

Revision One takes out the BK relay and the 12V relay.
I hooked up the trailer to the bus this afternoon. The discovery is the relay
(BK relay) comes out of the mixture. Greg O'Connor is correct...the trailer
brake controller will not function correctly with a relay. The trailer brake
controller wire should be wired only through the fuse block, allowing variable
voltage to the trailer brakes. The new Tekonsha Prodigy brake controller is
working fine after this change.

Greg,



You are absolutely correct. Use no relay for the trailer brakes. I've changed
the brake wiring and all is fine, and will change my write up and republish it.
The 12V relay also comes out of the mix. I'll cover that in my write up
as well.

Is BK Brake or stop
light? I dont think you van transulate the

variable voltage from the Brake controller thru a relay. 3 volts in is

12 volts out.
