ac to plugs, no air or lights, HELP!!!!

It has a new Progressive Dynamics 80 Watt converter that is putting out voltage. (I changed a working WFCO 75 watt for no reason, yikes). On the AC side we have power to the outlets but no lights, air conditioning, or power for the refrig. I don't think we have anything on the 12 volt side.

Where do I start???

AC breakers are where to start.

They can be tripped and not really look like it. Turn them off and back on.

If the air conditioner is controlled by knobs and switches on the unit itself, there is no 12 volt power required for it to run, so the 12 volt stuff is not a factor.

I think you meant to say 80 amp.
If you changed out the converter and now nothing works on the 12 volt side. I'd say you did something wrong.
Do you have 120 volt AC. Power to the converter?
Do you have 12-14 volts on the output of the converter?
Can you post pics of your setup?
Have you checked the reverse polarity fuses in the converter? They are the larger fuses. Usually off to one side.

Any interest in selling the unit you removed????

Yes We're leaving in the morning but I'll contact you when I return.

Thanks

To all who replied to my questions - Thank you very much for trying to help.

We we're successful in resolving the problem. As it turned out the battery was shot. We bought a new one and everything is working fine now.

Here are my FYI so that you can learn from my mistakes.

1) To start trouble shooting the DC side of the problem we connected the AS to the TV. As soon as we did that we got lights and the AC unit started to work. This led me to checking the battery. Although the battery measured 12 VDC there was insufficient energy stored to get any readings when tested.

2) We have a Dometic AC with a thermostat on the wall. I found out that this thermostat is actually powered by 12 VDC, who knew?

3) The converter will act as though it isn't putting out any voltage but if measured when disconnected to the battery you'll get the voltage readouts.

4) I still don't know why the lights didn't work on AC without the battery, I can only assume that without the 12 VDC side they won't work at all.

Again thank you to all who replied

We're off to Cali tomorrow morning because of your help.

The lights in the coach are 12 volt. If the old battery was shorted somehow it would cause the converter to shut down (crowbar) until the overload was cleared.
Are you sure you have 12 volts when not connected to the TV and plugged into shore power?
