My guess would be that your trailer is sitting a little nose down which is putting excessive wear on the front axle instead of the rear. If you look at the trailer when hooked up does the suspension equalizer sit level or is it angled? If it's not level this would show it's not sitting level. I attached a help article on picking out ball mounts as well. view full answer...
Hey Mark,
What gauge wire did you use to run from the junction box to the brake assemblies? If you didn't use at least 10AWG wire # 10-1-1 that could explain the heat build up and voltage drop. I don't recommend leaving the manual override clamped for long periods of time. I recommend reconnecting your brake assemblies, activating the manual override, and then then testing both wires coming from the brake magnets to see if there's voltage on both wires. Only one should have voltage and... view full answer...
Hey Eric, with that much voltage drop the issue is that the wire length added way too much resistance. The only solution is heavier gauge wire everywhere most likely. I would think that 8 gauge wire would be pretty close if wired everywhere but you might be looking at needing 6 gauge since there's just so much wire. You also need to make sure the ground wires are of an equal gauge too. view full answer...
Hey Mark, normally what you described would indicate that the blue wire of the P3 part # 90195 that runs to the truck 7-way has an open ground that is shorting to something metal on the truck. Since the wiring was checked the first thing to try is a reset of the controller which is just unplugging and plugging it back in.
If that doesn't fix it then a new controller would be only solution. view full answer...
Hello Gregg, I think I can help shed some light on what is going on. Basically, there are two ways to stop surge brakes from actuating when backing up the trailer.
The first and most popular way to do this is to use a surge brake actuator with a reverse lockout. For example, the Dexter DX7.5L A-60 Brake Actuator# DX56FR has an electric lockout. The solenoid is wired to the reverse light circuit on the tow vehicle. This way when the vehicle is put in reverse, the actuator will be locked... view full answer...
Hey Tim, it sounds like your Grand Design may have electric over hydraulic brakes but I am not totally sure. If that's true make sure your brake controller is put in hydraulic mode. Otherwise an aftermarket brake controller that was designed to be used with EOH brakes like the part # 90885 would be a great solution. view full answer...
Ford F-150's are an odd bunch when it comes to connecting to trailer wiring for some reason. While we haven't seen this exact issue it does not surprise me. It typically has to do with the 12 volt accessory circuit of the trailer wiring though so that would be where I would be inclined to start. If trailer has aluminum frame make sure you have a jumper wire from the ground harness back to the trailer wiring connector. view full answer...
Thanks for your continued support, Ryan!
While it's normal to be able to hear electric brake drums, like your Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-464, humming when power is being applied to them, I recommend trying to physically move your trailer tires before investigating every inch of your wiring and magnets (which would be the next step).
Sometimes the magnets can be a little quiet so what I recommend doing is lifting your trailer up by the frame enough for the... view full answer...
