Problems with new converter

I have a 1998, 29 foot Winnebago Minnie Winnie. Several months ago, with some help from this forum, I upgraded the converter to a PD4635V (from a Magnetek 6300 series).

Worked like a charm until last week, when it stopped charging the batteries. Here are the details:

- The converter is getting AC power fine, but is not outputting DC power.

- All ATC fuses on the front are good.

- The batteries charge fine from the car engine.

Any suggestions for troubleshooting, before I contact Progressive Dynamics?

Thanks,

- Andy

    I found loose fuse holder connection that was causing a loss of converter output to the house battery, while looking for burnt fuses. Check tightness of allen head set screws at converter case that clamp onto heavy guage wires that connect to the house battery(s) Check all positive and ground connections that go to and from the house batteries. You can also check whether converter/charger is outputting power by touching the allen head screws on the connectors on the converter case with your voltmeter probes. Set voltmeter on 20 volt DC range. It would probably be worth your while to replace your old converter with a modern converter charger that will charge, but not over charge and boil out your house battery electrolyte.


    Which is exactly what the OP has already done by installing the new Progressive Dynamics Converter.......... but it failed.

  • I tried everything, but no love. So I called Progressive Dynamics and after having me run a couple of quick checks, they just sent me out a new one. Once I get it in, I will send back the old one. They covered postage both ways.

  • If those fuses checked good with a meter (not just visual) I am thinking warranty time.
  • Verify you have 120V AC input to converter

    Remove both reverse polarity fuses (30A)

    With 120V AC input......test DC output at the battery pos/neg cable terminals
    DC output should be 13.2V Minimum

    If less..call Progressive Dynamics S/B 2 yr warranty
  • Be sure you've troubleshooted from the manual before calling.
