To all…
I had a local Cruisair dealer come to my boat and fix my A/C. I believe he said the High pressure switch was stuck open. Instead of taking out the old, which he said can be laborsom, he just by-passed it with another part that he had. Sorry this is pretty vague, but I can't remember all the pieces he was taking about…and it was 2 months ago.
Regardless, he fixed it and it has worked great since.

Yep…Thanks for the re-inforcement, and as I described starting in post 4 of this thread…That's what you can do…

Sorry All…If I didn't make it clear enough…

The answer is a new switch, but to leave the old one intact, and moving it's wires to the new switch…Just screw a new (screw on style) switch onto the high side service port…The tee would be so that you could still connect a gauge hose without removing the new switch to do so…The extra port of the tee would normally have a screw on cap just as the gauge port does now.

Hi back agsin Steve and thanks also to whywait,
The T worked fine but now the real fun starts. I also change the heat O/L with one rated for 1hp. I have always used a heatsinked paste on reefer compressors but since nothing was on the one I broke it didn't occur to me to get some when I bought the T's and HP switch/.
My compresssor is burning up. Not egg frying more like well done steak. And the air flow is about room temp.
The only thing I did was blow out a little gas from the high side. this seemed to cause air out temp change about 12 degrees higher. The hot compressor being why I let some out. Possibly the wrong thing to do from reading some other entry's. Perhaps the god's do not want me to have A/C above an outside 80f limit.
It sounds (Compressor) fine but is burning up. What what could cause that. /Is it on it's way out? Air in the system Undercharged? Please wave your magic wand of wisdom so I can get some cold.
Thanks for your support.
