Is there a way to test the power converter?

In my 78 Sovereign, the power converter hums when plugged in but unless the batteries are connected, there's no voltage read anywhere on the fuse panel. Is this by design? The AC power LED on the control panel lights up regardless of whether shore power is plugged in or not.

For more clarity. The batteries are disconnected and the shore power is hot along with the power converter.

Every light/fan works when the batteries are connected. Nothing when they're not.

If the main fuses from the converter are not blown, it sounds like your converter is dead. I had one do that at one time, hummed but no output. They are essentially obsolete anyway, and time to replace with a modern three stage converter/charger such as the Progressive Dynamics 9245 or 9260. There are other types available, I simply have experience with the PD units and find them very good at a low price.

The power on light you have which is always on must have been re wired somehow by a PO. It works directly from the original "univolt" converter and only should be on when it is working, and plugged into 120 volts. To my knowledge, there is no way to make it work as it did originally once you replace the original "univolt" converter. A little neon nightlight from the hardware store can easily be plugged into an outlet and will work as a replacement.

Thanks for your input! For the record, this is the control panel I have and the AC Power LED doesn't illuminate until you push the button. Problem for me is it lights when the batteries are connected but the power converter isn't.

Question

first question....is it the original OEM converter?

If not, as noted above, it's likely the PO has re-wired it.

What's the battery voltage, disconnected?, connected with converter plugged in?...14.2v min.

Do the panel lights work when you push the "test" button?

Thanks Bob. I believe it to be the original converter, all I can make out is TU-470-6 on the box.

It's definitely not putting anything out as all hot leads read 12.4V. The LEDs do work when the button is pushed.

My advise "ask Randy"...looks like it's time for a new 'verter.

This is the one we got from him...excellent unit and great customer service.

Pd9260

I just installed a Progressive Dynamics 9260. The old univolt had 4 wires. positive, negative, a ground, and a small black wire that came from the fuse panel.

1985 Airstream

What do I do with the little black wire

It is not hooked up, but everything seems to work.

The small black wire may have been for the "Power on" light. There is no where to put it on a PD 9260 so the light will not operate.
