Replace converter/charger with PD9245C

My electrical guru is out having fun and this is not clear to me. I removed the converter/charger from a Centurion 3000, leaving the fuses and circuit breakers.

I need to tie in the 12V positive output from the PD9245C, but not sure where I should tie it in??



  • Posting pictures on this page is a pain, even when knowing how to do it.

    I have installed these before and it should not be an issue but when I got to the disconnect it might as well have been a Flux capacitor and see no reason for it. I will connect to #1 and if it ever becomes an issue will change it to the other side. Actually if it ever becomes an issue I will remove the disconnect as I use manual breakers so disconnecting a battery is not an issue for me.

    #10 is too light as the tables call for #6!

    As long as I have everyones attention where did you connect the neg output of the converter charger. Also I seem to recall that the the chassis ground of the converter is best connected to the actual vehicle chassis?
  • I disagree, it should be placed at the arrow.

    if you have to isolate the battery circuit for whatever reason, you have now lost all 12v capability even if plugged into 120v.

    a PD can also put out 48amps, thats a bit high for 10gauge.

  • Here's the picture! This should be pretty clear.
    (Thanks, now I know how to do this.)
  • Thanks for the input, greatly appreciated. Seems the more birthdays I have the more easily confused I become.
  • JJRBus,

    This is really a lot easier than you might expect.

    I can't get my picture to post, so...
    Follow the cable that goes from the left terminal of the disconnect to a Circuit breaker then on the next circuit breaker that connects to the house bank.
    Connect any place along there that is convenient and safe. If the cable is protected, it will not need a fuse because the cable that is there is protected and the PD9245 has fuses in its own output.

    If you put the pendant someplace you can see it, you will know what the converter is doing all the time.

  • you should be tieing back into the distribution panel, where the original charger provided power, pd converter should be the load side of the battery disconnect. at least thats how i did it, so i could disconnect the battery's and still have power, but i tied into the distribution panel directly as it was sized properly
  • I would wire the converter with a fuse or CB to the house battery wire. I'd also add a fuse/CB from the isolator to the chassis battery. This assumes that the existing wires are adequate for the new charger.

    A 50A fuse/CB for a 45A charger might be marginal due to loads and tolerances.
  • I had this same issue. How did the converter power the dc side? It turned out the dc power is from the battery bank and I did not replace those wires. It seems to work! My wiring story. Twinsprings Blog
