Recommended Trailer Wiring To Charge Battery And Use Solar Panels  

I went to our warehouse to provide you a few measurements of the Pro Series pipe mount swivel jack #PS1401080303. The length of the entire swivel jack in the retracted position is 26-3/4 inches. The foot plate is 3-3/4 inches wide and 7-1/2 inches…

The etrailer brand #TJP-2002S-B is manufactured in China. We do offer some side mount trailer jacks from Dutton-Lainson that are manufactured in the USA. They don't offer a pipe mount jack, but they do offer a swivel pin mounted jack which would…

While unlikely, it is certainly possible that the trailer battery could backfeed to your vehicle's battery when hooked up under the scenario you described. To make sure this doesn't happen all you need to do is add a single diode like the…

If you wanted to make your 12 volt power circuit turn off when the vehicle is turned off you could install the isolation solenoid part #PK5231201 on the circuit. You'd need install the circuit to the outside posts and then for the center pin…

If the 12V power for the 7-Way connector is active it will pull power when the vehicle is off and installing a Battery Isolation Solenoid #PK5231201 would definitely help you avoid this situation and keep your cargo trailer interior lights running…

Since your 7-way connector is only hot when the key is turned on, a battery isolator solenoid would not be necessary. Since this is not the case with all vehicles, it may be good practice to unplug the trailer from the vehicle when not being used.

You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7-way. The 1:00 position of your 7-way carries this circuit. You would just need to run a length of 10 gauge wire like part #10-1-1 (sold by the foot),…

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…

You would not be able to charge your battery through the wiring on your 4-way trailer connector. Since your truck has a 7-way connector, you could maintain the power to the battery but not charge it. To begin, you would need to cut off your 4-way…

Hey Phil, It's ok to see 12 volts on one specific pin (pictured below). It means that whoever wired it ran a line to the battery so that the 12v hot pin on your tow vehicle's 7-way can charge the trailer battery a bit while you tow. Power…

On the output post of your dual alternators you will need to run a thick gauge wire from there to the positive post of the batteries you plan on installing in the tool box of your truck. This will put a decent charge on those batteries while you are…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
