Checking Out the Roadmaster Hy-Power Diode Video

I checked with Roadmaster and none of the many models of the 2022 Ram 1500 require a charge line to keep the battery from dying. You can always add one using the Roadmaster Battery Charge Line Kit item #RM-156-25 if you're concerned about…

Yes, the Hopkins Tow Bar Wiring Kit part #HM77VR is a confirmed fit for your 2022 Ford F-150 platinum hybrid.

A diode is designed to stop the reverse flow of current in an electrical circuit. Therefore yes, a diode will prevent backfeed to your vehicle from the trailer's battery. The part you referenced part #RM-790 has a dual in, single out function…

4WD models of the 2022 Ram 1500 are able to be flat towed, with a few steps listed in the owner's manual. TO flat tow your Ram you'll need a baseplate, tow bar, tow bar wiring kit, braking system, and safety cables. For these components I…

The factory trailer brake controllers are not good options for trailers with electric over hydraulic brakes. There are adapters that you can use to be made compatible, the HydraStar Electric Over Hydraulic Actuator Adapter Module part #HBA-CAM but…

If nothing at all is working then the ground wire for your Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit #RM-15267 is likely the issue. I recommend checking that it's making a good connection to the frame of the vehicle and isn't…

To flat tow your 2018 Ram 1500 you'll need a base plate kit installed first. For that you'll want the #BLU74FR for if you have a Big Horn, Laramie, or Rebel. If you have a Sport or Express instead you'd want the part #BX2409. You'll…

The importance of matching a wheel's pilot hole diameter to the part of the hub that fits through it depends on the type of wheel. A hub-centric wheel uses the pilot hole to center the wheel on the hub and also to bear some of the total weight…

Installation of the #RM-790 will take care of that problem you're having. I would wire it on the trailer side at the battery rather than mess with the wiring on your 2024 Sierra 2500. The other solution is to follow the GM note and add a…

The correct way to wire up the breaker that comes with the Roadmaster charge line kit part #RM-156-25 is to have the copper post ran to the positive post of the battery that is charging the other vehicle and the silver side to the battery that is…

Your black drawing would be how wire up the #RM-790 so that both batteries would be on the same circuit but with feedback prevented on the circuits back to the batteries or having them tied together. Basically you would use a diode on each battery…

Yes, you will want to use a single function diode, like part #RM-690. You will need to wire it in between the breakaway battery and the trailer battery to stop the backfeeding from the battery to the breakaway system.
