Progressive power converter problem pd-7648

[Buster52]

I have a Progressive that I believe is giving me problems. It acts like it is not charging the battery. Opened it up and find 12 volt power to about 2/3 of the fuses. But the side that powers the heater, pump and battery is dead. I understand it maybe the pc board that I cannot find a replacement for. Is there something else that maybe wrong with it? Does anyone know where I can find the board, or what can I replace the 12 converter with? Any help?

Thanks

Buster

I want to thank all the advice I have received. I have fixed the problem with a tooth pick. That is right a tooth pick. That was after removing to unit and putting it on a table. The battery charger part is a SCR that is controlled by a circuit board. The board had power but it wasn't making it to the SCR. A squirt of contact cleaner and running a tooth pick through the connector pins and now it is alive. And next thing is putting it back in and connecting all the wires. If it goes out again I will just replace it. Thanks Again

Have you called PD they are in Michigan and they can recommend a replacement.

If you want to make friends with communist countries buy a WFCO. If you want a good converter dont buy a WFCO, buy something better like a new PD. Some upgrades come with a new fuse panel.

That old PD-7648 is a 1970's technology.....

In your 1989 RV it's 25 yrs. old.

Time for an upgrade....new converter.

As suggested.......talk with Randy at Best Converter LINK

Did you try calling Best converter?

I looked for a direct replacement and found none. I can get manuals on it but cannot find parts or replacement for it.

Maybe this will help
Manual
Some of these older units have two outputs, one clean and one dirty.
I would suggest getting a direct replacement converter section from Best converter. It could save a lot of headaches.
