I have a 2003 38 Open with 2 Marine Air A/C units and the following description is the way they are rigged... On the main power panel there are 3 breakers. One for the Sea Water Pump and one for each unit... If the Sea Water Pump breaker is off or if the Sea Water Pump fails to start/run the unit(s) will shut down (a code is displayed on the digital control panel). Just because water is coming out doesn't mean the A/C compressor is working correctly. All it means is the Sea Water Pump is functioning and told to come on via the A/C pump relay.... M2C
