Hi, need some advice from you brake controller experts:
I have this trailer dolly from Harbor Freight:
Heavy Duty Trailer Dolly
It works great on a level surface. But when I roll our 13' Scamp
to its parking spot next to the garage, there is a slight decline I have to go down. I can muscle it with someone helping holding it back so it doesn't get moving too fast and run me over, but it's a little sketchy and so I had the idea of controlling the Scamp brakes
by adding a button to this dolly.
But I'm not exactly sure how to go about it. Any ideas? I can run a wire from the trailer battery
up to a push button switch on the dolly handle, and then a wire back down to the brake terminal on the trailer plug. Then hold the switch closed when I want to apply the trailer brakes
. But I'm not sure if a direct 12V connection to the brakes
is ok. Do I need to find some kind of thumb-operated potentiometer to vary the resistance? Hmmm...I suppose I could just by a cheap brake controller and attach it to the dolly handle, but I was hoping to make this even simpler.
Any ideas? Am I crazy??
