Is the gain on the controller set all the way up? If it's set to 3.5v as the max that's as far as it will go with the lever or the brake pedal. Try maxing out all of the adjustment setting to see if that changes anything. What brake…

We recommended to repack the wheel bearings on your trailer every 12 months or 12,000 miles. There is not a specific guideline as far as actually replacing the bearings. When repacking them with grease, you will also just want to check for any damage…

Answer 8

You really should have around 12 volts at the junction box and then about the same at the axles. That amount of voltage drop is most likely due to using wire for the circuit that is too light. Especially since you said you have three axles. I'd…

I am not entirely sure what process you took so I'll give you some other things to try, or maybe a different way to test the Prodigy P3 #90195. First, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester…

It could be a tow package fuse on the vehicle. Use the owners manual to find the locations of fuses/relays related to the tow package wiring to check them and replace as needed. If the issue is not a fuse or relay then you can test the vehicle side…
