I found the problem. The wire at the ledt rear brake drum had been cut and from looking at it I believe that it was cut with a knife. Disgruntled employee? Anyway, easy to splice together and now works like it should.
I own a 2012 Avalanche RL290 by Keystone. I purchased this rig in Jan 2012 so it is out of warranty. Due to health problems, my wife and I were unable to use it until recently when we took it on a short trip. I noticed that applying the brakes did not do very much to slow the rig down. I could feel the brakes engage and I went to emergency stop on the Prodigy brake controller but the braking action was no better than just stepping on the pedal. I worked the brakes hard several times and finally pulled over to ckeck things out. I found that the brakes on the two front wheels were hot (as they should be) but the rear brakes were were not hot at all. I believe the brakes on the rear wheels are not hooked up. So my problem is that with no warranty, the dealer will charge me to connect the brakes properly. I guess I will object to that and contact Keystone and maybe a lawyer.
I wanted to check the wiring out myself but the wiring disappers into the cover that covers the bottom of the trailer. Does anyone have a recent Keystone that knows where the front wheel and rear wheel wires come together? I figure the problem is at that point since the front brakes work fine. I did test the rear brake wires with a circuit tester light and no power is getting to them.
Any help or suggestions would be appreciated.
