Battery Management System for Camper in GMC Sierra That Can Charge from Solar/Alternator/Shore  

The crank handle for the Lippert Components Spare Tire Winch with Offset Cable item #LC159056, is Replacement Crank Extension for Lippert Spare Tire Winch Assemblies - 35-1/2" item #LC1315411. The Spare Tire Winch item #LC159056 has a 1/2-inch…

I reached out to my contact at Redarc and confirmed that when using the In-Vehicle BCDC Battery Charger #331-BCDC1225D the only benefit is the increased amperage when you connect the unit to the alternator versus the battery directly. This is a big…

For this application you will want to use the Redarc In-Vehicle BCDC Battery Charger #331-BCDC1225D. This will give you a clear input for your solar panel and alternator and a clear positive output to your two 6V batteries run in series and to…

You will need a battery isolator, like Battery Isolation Solenoid, part #PK5231201, if you plan on leaving the trailer connected to the truck when the truck is off. If you unplug the 7-Way, the trailer battery cannot drain the truck battery. If you…

If all you want is to prevent the 12 volt power supply of your trailer battery wiring from backfeeding onto your vehicle wiring or vice versa what you need is a one-way diode like part #RM-690. This only allows current to flow in one direction so…

If you are using the 7-way auxillary pin on your 7-way for your trailer battery, it will not provide enough current to charge the battery. When hooked to the 7-way from your truck it will only maintain the charge on a battery. You will need to charge…

The 12 volt power circuit of your 7-way would not be able to charge a dead trailer battery, but it can put a light maintenance charge on it so that it stays topped off while you are travelling. The circuit is most likely protected by a 40 amp fuse,…

If you installed a decently sized deep cycle battery on your trailer you wouldn't have a problem powering the LED lights of it for the length of time mentioned since LED lights draw a fraction of the amperage as incandescent. Group 24, 27, and 31…

You'll need to add at minimum 1 battery and you could add as many as 3 since solar systems of this size typically recommend between 4-6 house batteries to store all of the power produced by almost 800w of solar panels. For reference, the Go Power…

You can indeed test a trailer's electric drum brakes by directly applying +12V power from a fully-charged battery. You can apply this power to the hot and ground contacts on the trailer's plug (see photo please) or to an individual brake…

I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further…

There are a few different tests that can be done to check the brake magnets individually and as a whole on your trailer. I would first recommend checking the magnets for wear before going on to test for proper amperage. If the magnets show abnormal…
