I'm going to have to swallow my pride here and admit to some boneheadedness in the hopes it keeps some other poor soul from going the route I just went. :ugeek:
I pulled every fuse in the box that was either 10A or 15A, thinking the factory may have sistered onto some existing circuit to power the freshwater pump. Yes, my fuse box did have a "F/W" fuse which was 15A (the factory must have figured it out by 2020, Peter, and installed a 15A fuse). All fuses checked out. On to the wiring and connections....
Getting my 6'4" frame contorted into every nook to check each connection I could find, I finally decided that all connections were good. Pulled the switch at the galley sink, and it checked out fine. I continued scratching my head...
Got my booklets out from the factory... no help there.
OK, it HAS to be the pump, right? But dag-nabbit, the freakin' pump is held down with square drive screws, which I failed to have with me. So... continued head scratching.
Viola! A thought! (an unlikely one, but I had to think outside the box at this point) Maybe... just maybe, the factory figured out a way to keep the pump from running dry by putting a low-water cutoff in the tank? Never heard of such a thing... but I'm out of options until I get my square drive bits to replace the pump. I was 'sure' that I had a quarter tank of water, but it's possible that I could have been wrong. Unlikely, but possible :mrgreen: So, I just bit the bullet and started filling the tank to about 1/2 to 2/3 full.
Got back inside... hit the switch... NOTHING. So frustrated! OK, it's the dang pump. A pump with only about 12 cycles to it's life... but sometimes ya just get a bad pump. Gotta be it.
Staring at the galley sink and faucet in disbelief that I had to replace the pump so soon... I just happened to push the faucet's lever up - just for S&G's. The pump KICKED ON!!!!
Turns out there was nothing wrong at all... anywhere. It was the perfect storm: So little water in the tank that the gauge failed to move - and a super-watertight system that, even after a couple months of holding pressure, didn't bleed off any pressure at all... Amazing!
So, when I kicked on the switch, I expected to have the pump cycle on shortly to recharge the pressure - like every other boat I ever owned. When the pump failed to kick on with the switch - coupled with the needle of the gauge not budging (because I wrongly assumed the tank was 1/4 full)... I incorrectly assumed the system had a problem.
All I had to do is turn on the freakin' faucet! :ugeek: :roll:
Thanks for letting me vent! And for having a venue such as this to get so much info! 😀
