Prodigy P3 Overload Warning
I am getting an intermittent overload warning on my P3 controller that just started about 500 miles ago during our last trip. I would like to get it resolved to get us back and then R&R the whole sys...

The wiring has been completed. No telling how long I have been running with only 75% braking. I found that on the right front one of the magnet wires was out of the original factory crimped connection. Before I started, measuring with my Fluke meter, the brakes measured 1.5 ohms at the trailer connector. After the rewire the measurement is 1.1 ohms. It will now be really easy to isolate a magnet. Hope to take it out for a spin tomorrow to see if I helped the overload alarm.
Two things.
First you need to replace the wire nuts with waterproof crimps.
Wire nuts will allow the connections to corrode and will not be able to handle the vibration they will be exposed to.
Second the P3 has a diagonistic feature that will give the current drawn by the brakes.
I have found the current will be very close to 1 amp per volt applied.
This correlates close to the resistance you measured.
I check the voltage applied and current drawn before every trip with the manual lever on my P3.
