Speaking of Brake Controllers, I got a problem with mine..

Posted

I have a drawtite activator II (part number 5500) and it can be set from 0-10 with the LED thing and it works by ramping up the brakes to that level. So when I hit the brake pedal, it ramps up to 8 if it is set there. Well lately it ramps up and eventually overloads ("ol" on the screen) while it is still ramping and then it just starts at 0 again. You can feel the trailer start to drag as it ramps then it lets off, does this over and over always overloading. Just recently started doing that crap. If I turn the level down to 5 or so, it doesn't overload.

To me is sounds like its not getting enough power to run the trailer brakes ramped up to 8, so maybe theres a wire thats not tight, corroded wire or something. that would be my best guess.

I'll add it to my rewiring list then. I know those wires are questionable from what I can see by the hitch.

Unless there is a bad magnet in the hub that not quite shorted out but got issues... OL - Overload - High Current Draw So in my mine I'd look towards the magnets and might have to open the wiring up under the trailer and test each magnet for amp draw. See if you got one magnet that is drawing a bit heavy...

An amp gauge for the trailer brakes, now that would be neat! Have to try that out.

100% agreed.

That's something I can look at in my PIII.
