Troubleshooting No Power On The DC Side Of The Progressive Dynamics PD4135K Power Center  

Question:

Expert Reply:

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.

@KevinC Not sure what is going on, had to disconnect lighting for interior ceiling repairs and now I cannot get 12v lights to work. Hooked up 110v it works fine.

@WmZ Another question, I switched S1 on for lithium that I am getting ready to install and the green blinking light when out. But I have 110 power as A/C came on. Still no 12v lights

@WmZ Where did you disconnect the wires at? It not working when on 12v but working when hooked up to shore power tells me that the lights might not have been hooked back up to the appropriate wire on the back of the unit and there's an issue with the fuse. When hooked to shore power the converter overrides the battery and powers the DC distribution panel in the # PD4135K. This is most likely just a simple wiring issue.

@WmZ The indicator light is there to show what charging mode you're in based on the speed of blinks. This only works on lead acid mode so you wouldn't see the light change in lithium mode.
