I have a 2005 Hunter 45cc. Does anyone knows the location of the trigger switch (relay) for the air conditioners sea water pump
Ok,, here’s what Hunter did on the 49s, which I assume is the same on your boat.
The cooling water on the airco units runs in series through the airco units. So, if any airco is on, water flows through all units
The way this happens is there is a relay box that switches on when any of the airco units are energized. The water pump is powered from the contacts on these relays, which are essentially in parallel
Hope that helps !
