1985 61MY 3/4 full warning lights all 4 illuminate constantly. Trying to locate the par pressure switch. I can see the location where the tube exits the holding tank but because of the location (behind the aft generator) I can’t get to it to trace the tube.I have checked all hatches in generator room, forward bilge area and starboard bilge area with no luck…The search continues

Re: Par Pressure Switch location
On my 67 cmy, the holding tank is the farthest forward tank. Port side forward of the forward generator (almost to the fwd bulkhead) is where the copper tube protrudes to a diaphragm pressure switch. A bit inboard of the stringer / shelf for the compressor / condenser skids. Sam’s has replacement tubes and pressure switches.

Re: Par Pressure Switch location
Thank you…. I have been all over/under the generator room to no avail. I can locate the tube exiting the tank (again located just aft of the aft generator). With limited access between generator and aft bulkhead I can trace the tube about a foot only…. It appears to run along the bulkhead towards starboard side and then I lose it…. I have checked the mid head sump area, starboard bilge, all cabinets in washer/dryer area with no luck. Stairs from lower companionway to “office” formerly crew mess are solid, no storage. Possibly in the washer/dryer access area which you enter from under former crew galley table? I have been in there a couple of times and don’t recall seeing anything, but at the time wasn’t looking for it either.

Re: Par Pressure Switch location
I do have a WEMA sender and gauge installed to monitor the system which works great. Just my OCD says if it's on the boat, I want it to work, sooooo I have 4 lights in heads that stay on all the time (of course bulbs are removed currently) so we are not in the "Red Light District"...

Re: Par Pressure Switch location
I have installed a Maretron ultrasonic tank monitor on top of the holding tank by taking a plug out of the tee that hooks to the pump out hose . Works great. I still have the 3/4 light working, but the monitor lets you see where you are as the tank is filling. Also you can push the tank after the light comes on , but stop short of over filling.
