Dunny is on the blink
 

Yo,
Anyone had trouble with their head in the 38ZR?
Ours appears to have no power.
I've checked the breakers above the sink in the cabin, the breakers under the helm and those next to the battery switch.
Nuthin looks bad.
It simply does nothing.
Any clues?
Cheers

Put a multimeter on the pump itself to confirm it is getting power, then work backwards from there if there is no power.

smart !!! (now I feel silly) Thanks...
Cheers

OK, seems like I have worked it out. Does anyone here have a 38ZR with a vaccuhead toilet?

In the engine bay, on the port side is a fresh water filler, starboard, a waste filler. I put water in the waste filler and now the toilet works fine.

Is this a tank for input water for the toilet or is something funky going on?

I open a ball valve that pipes the water straight out the starboard side of the boat when you flush it. But way back near the engine bay.

Confusing.
