When you installed your Progressive Dynamics RV Power Control Center # PD4135K did you insert your DC fuses into the ports to complete the DC side of the installation? If you did I recommend doublechecking that they haven't been blown. There's an indicator light above each fuse to alert you when they have been blown.

You'll also need to ensure that the Converter White, Black, And Green wires have all been properly installed, otherwise you'll have no AC power running through the converter to the DC fuse board. I've attached a wiring diagram to help you with this.

If you've checked all of this and still can't get your DC fuse board powered then let me know and we can keep troubleshooting.

Coming out of the back of the power center you'll see two red wires, five black wires, and one white wire. This white wire needs to be grounded to the chassis of the trailer. If not your DC fuse board will not properly operate. It's very common for people to just run it to the ground bar located on the AC side of the power center, but is the incorrect way to wire the system.
