2016 HL Ranger xp900

I added a set of rear LED work lights to the ranger and after about 5 minutes i lost all power to switches. I have checked and the keyed hot post on the terminal block under the hood has no PWR now. I have checked all the fuses and everything looks good, 12v acc plugs in dash are working and hot post on terminal block works.

I have called 2 dealers and spoke with the service department and they both say the only thing that is in line to the keyed hot post is the acc fuse, however i have read that there is additional fuses wrapped in the loom can anyone confirm what the wiring is to the keyed hot post on the terminal block?

Ranger starts with out problem but now i also have a CHK Eng Code 520207 5 (Driver Circuit Open / Grounded 5 P1836) not sure if this is a relay or not but any help is appreciated.

Welcome to PRC! In addition to the fuse, there is a relay in your fuse box (labeled 'Chassis') that also controls that circuit but since your accessory plugs in the cab work, I doubt that is your problem. Just to be sure, however, swap your chassis relay with one of the others in the fuse box (they are all the same) and see if the problems moves to somewhere else.

Next, completely disconnect your LED work lights. Disconnect your neg terminal on your battery for about 15 minutes to clear your check eng code. Reconnect your neg terminal and see of the check eng light comes back on. If it does, you have a short somewhere in your wiring -- and it will probably be a bugger to find! If it doesn't come back on, you probably have a problem with your cube wiring.

Your front diff also gets power from the chassis (accessory) circuit. Check for power (key in 'on' position) on the two wires that feed it and, of course, check the plug for a good, clean connection. If the plug checks out, reassemble using dielectric grease.

Let us know what you find, and don't be shy with the details!!

A good part of the time, the full power terminal on the Rangers is not connected from the factory.
You will need to connect it. Looking down at your solenoid, the left side is the full time
12v side, the Right is the keyed side. Connect the ones you need for the buss bar to work. If none
are connected choose whatever terminal you want. For Ground run a wire from one of the terminals
to a ground point on the frame. I went about 3 inches with a wire and drilled a hole into the metal
and attached a wire.
