A/C Water Pump Relay

[Sudsy 38]

I recently purchased a 2000 Sea Ray 380 Sundancer and have been experiencing some issues with one of the air conditioners . After some investigating it appears that the water pump relay isn't working for one of the ac units . It took me a while to find where the relay is located and it appears that the previous owner had opened the box and has made a mess and may have hot wired the pump so only one of the ac units will trigger the pump . I just wanted to check if anyone has accessed the relay box in the engine room and if there should be 2 triggers located on some type of circuit board ?
There is just some wires spliced together on my boat and it appears that one of the black wires is missing ? If anyone has dealt with this issue and can provide any insight it would be greatly appreciated .

Thanks CaptRonn!

I found the Relay Junction box in the engine room and it doesn't look like this one . It seems the previous owner had issues and removed the circuit board that held the triggers and has wired the pump directly to the Forward air conditioner .If I start the rear unit it won't start the water pump . It's a real mess !

It's hard to guess what the previous owner was up to, but I wonder if the aft unit took a crap. Mine did and started blowing breakers and then the compressor 'done died' after a banshee wail. I had to actually disconnect the neutral leads to even power the boat up. (replacing it this Fall).

So are you sure the aft A/C even works? Maybe that was his answer to a similar problem?>> Just tossing it out there.

I can confirm that both unit work . If I drop the thermostats on both units way down and start the fwd ac first it kicks in the water pump and blows lots of cold air . At same time if I turn on the aft ac it will blow lots of cold air until the fwd unit reaches the temp set and then it turns off and eventually the aft unit shuts down due to no water flow .
