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.
