I am installing a Progressive Dynamics PD4045 to replace the 25 year old Centurion CS3000 in my 1999 Jayco popup, and I have a question. The AC side of things is working, all of the outlets are as they should be, but I can't get the 12VDC to work. Since there are no installation instructions as far as how to use the black wires coming from the back of the converter, I assumed that the black wire coming out of the back of the converter should be connected to the black wire from a 12VDC light, for example, and that the white wire from the light should be connected to the frame ground, which is in turn connected to the ground busbar in the converter (for shore power and the converter ground wire). What did I do wrong? I measure no DC voltage from the black wire coming out or the converter to either the ground busbar in the converter, or the neutral busbar (white wires for shore power and converter) in the converter. The fuses check out OK. I went through the troubleshooting guide available online from PD for this converter, and everything checks out, indicating that the converter itself is not defective. I'm at a loss, if anyone can help.

(Note: I do not have a battery hooked up).
 
Have you checked te fuses on the board. If you happened to reverse connect or even has a loose wire these can blow. Also are the black wires hooked to the board? I see that there are two black leads that appear to be needed to be hooked up to the board. You would need the battery hooked up in order to supply power to the DC side. In my experience the battery is a key element in completing the power circuit. Maybe Kevin D. Pem can jump in here and add or correct me.

Problem solved on the Jayco Owners forum. Thanks for responding.
 
It sure would be nice to know WHAT solved the problem! Future problems might be solved also if the OP explained.

The DC board doesn't have a ground, as I had assumed it did since it was prewired with leads, etc. Unless you either ground it yourself or connect battery wiring to it (even though we don't have a battery installed), it won't work. I did both, since we did have the wiring for a battery.
