Oh and our 30/20 breaker is Bryant BRD BD 3020

Fitted into a Progressive Dynamics power converter PD768Q

Looking at the cover again the 30amp side is the "main" breaker and the "20amp" is the a/c circuit.

Ok sorry for the posting frenzy! But could it be the compressor getting too hot/drawing too much current & causing a voltage drop on the a/c circuit,hence the a/c sensing a low voltage situation?

Finally got up on the roof and changed out the old capacitors in an attempt to make sure everything else was as good as it could be. Had already seen the original caps had seen better days but still worked when putting a new fan motor in.

Anyway the Supco hard start cap & relay I got went in great.. started up great and ran strong until about 3pm when the compressor again kicked off & low voltage light was on

Voltage everywhere was again reading 118V AC, coming to the conclusion the only thing it can be is probably the compressor getting too hot due to age. Just when it gets to a certain temp//humidity and it craps out, other than that it is perfect. Checked "all wiring & connectors" no burning/melting or loose wires

Really thought this would be the main culprit!! How can you say "High resistance" from all that rust!!! But alas it wasn't the cause, at least its not part of it now.Maybe it never was.

Paul,
I went back thru the posts to see if you had a generator. If you do, try running it during the peak heat of the day and see if the A/C's stays running. The voltage from the generator should be better than the park's.

We have got an onan genny , just with the current fuel pump problem/lack of cranking issues with the motor home that are almost fixed we cant start the gen yet.

Would definitely try it though. So as soon as we can get the fuel pumps and or the relay & it all checks out will be firing the generator up asap.

Paul,
Be sure to take voltage readings from the generator when you get it started. I noticed you had a good deal of corrosion on the capacitor that was removed, how was the connection that was attached to it. What model Suppco did you install? Was it the SPP6E?

It was the Suppco SPP6 working fine .The spade connectors are fine just removed what light corrosion was on them, was weird most of it was on the capacitor connections.
