Today we are going to install part number BD500185 from Bulldog. This is their powered jack. The jack is ready for 4,000 pounds and it should be pretty easy to install. The first step involved is to remove the old jack and any accessories with it. We will lower the trailer on some jack stands. Get the jack loose. We have got a battery box for the brake away kit so lets take that apart and loose and out of the way. Once you have the stuff around the jack out of the way we will unbolt the jack from the tongue. Once we have got it unbolted we can pull it straight out. 00:43
We will install the power jack the same way we uninstalled the original jack. Line up the bolt holes, whichever ones match up the best. You have got a couple of different patterns on here. Get the wire out of the way. We are going to install the jack reusing the original hardware because of the higher grade than the original stuff that comes with the jack. We will reattach it that way. We can run the wiring out to the power supply. We will put our break away battery kit back into place. 01:14
Now we will run our power supply wire into our tool box in the trailer because the battery is hidden inside there. We have pulled our cable through the box. We will take the lid off our battery and what we will do next is wire our wire to go to the positive terminal on the battery. We are going to take a simple butt connector and just screw that on the end of the wire and just crimp on the extension. We will connect to our positive terminal now. Lets put our cap back on. We will actually run our ground wire to this bolt that we used to mount our battery box to. We have got our jack wired up. Lets install the jack foot itself. Slide it up into the jack. You have got holes in it for the snapper pin right here. Lets put the pin in and snap it into place and we are good to go. Lets give it a shot. It goes down and it goes up. With three little LED lights. With that, that will finish our install of part number BD500185 from Bulldog.
