Its been one of those seasons.

I purchased my 325 Carver in FEB 18. I immediately noticed upon acceptance what appeared to be an intermittent water flow problem while operating my two AC units. In the late spring I called for heat and in the summer it was strictly AC. I noticed some intermittent water flow stoppages during either operation. I have read that some units have relays working with the compressor to cycle on and off. I was never convinced my system was designed to do that. Most other Carver's in my marina seem to have constant water flow while the heat or AC system is on?

My two Passport II controls seem to work well. However I NO longer have water running through either unit and I do know my pump is not physically operating while wired into the system. When I located the Marine Air wiring junction box which appears to contain all the wiring for the two units, I noticed the previous owner had twist tied a "spare" 110V molded chord with exposed ends in what appears to have been an attempt to troubleshoot a pump? The spare chord was twist tied to the water pump 110v cable??? The surveyor apparently never noticed that? Anyway I suspect the pump is faulty and I will start troubleshooting the system this weekend as neither unit works right now but the controls do call for AC and both systems seem to initially fire up normally. Both units operate for about a minute and shut down as water is NOT pumping and I suspect that is what the system is looking for? I have removed the strainer basket and all is clear on the water line side. My plan is to start by disconnecting the pump wiring at the j-box and connect it to 110v to see if the pump works outside the controls. Any other suggestions are greatly appreciated.
