Ok, so excellent news...... my 2012 Ram 1500 still had fluctuating volts (0.07-1.4 volts) going to the blue wire at the junction box with all of the wiring disconnected for the brakes. My fathers 2014 Ram 1500 still had fluctuating voltage but his was only 0.00-0.02 volts which I thought was acceptable. (Both trucks have the factory integrated brake controllers.) We got everything hooked back up, I double checked the adjustment on the spindle nuts (tightened the nut and then loosened it without spinning the hub and hand tightened the nut backing off the nut to the closes area I could put the tang over into) , and also double checked the adjustment on the brakes (tightened up the shoes till the wheel would not spin either way, then backed off the star wheel 10 clicks). At this point, we still heard the magnets clicking on and off like a turn signal flasher would. According to the service department at Ram, this was the truck sensing the trailer. We took the truck out for a test drive with the trailer and had our 70 challenger convertible in the trailer for weight. We drove about maybe a half hour around my Dad's neighbor hood and stopped twice, checking the hub area with an infrared thermometer. I am happy to say that the brakes slowly heated up. First stop (about 10-15 mins into the drive) was 122-123 degrees on the driver side and the pass side was 118 degrees at the rear wheel, and 106 at the pass. side front wheel. At the second stop, the temps only slightly increased. I checked the hub temps when we returned home and we read 130 and 132 on the driver side (front / rear) and the pass side was 128 and 108 on the pass side. (rear / front). So I am happy with those numbers unless they are supposed to be a lot lower than that. The driver side did seem significantly cooler than the last time we test drove it. We also had the brake controller set at 6.5 by the end of the test drive. We started out at 8.5 and thought it was grabbing too much so we backed it down.
