I have a Teknosha "Voyager" electric brake controller mounted in the truck,,, on the right side is a wheel marked, "gain" on the left side is an unmarked wheel and facing me is a horizontal sliding bar that manually applies the trailer
brakes. There is also a
light that glows in red,yellow , orange, and green. When I step on the
brakes, nothing happens untill I've really mashed down hard, and then the trailer
brakes lock up. Can anyone enlighten me on how this thing should be adjusted? Tnx.
