No power to vacuflush pump

[Lenny3]

Head Breaker is ok, (removed panel and checked for DC voltage on both sides of breaker).
No power at + side of pressure switch. If I add 12v power to + side of switch the pump and pressure switch runs perfect.

Where does power wire go after is exits the breaker?

My advice would be to go on the searay.com website and download the owner’s manual. Wiring schematic is in the back.

I had the same problem but my solution was very simple, the key in the head needs to be in the on position to power the pump.

When I turn the key on in the head the macerator discharge pump runs

I would check the gauge sending unit mounted on/in tank. what is the the gauge showing.

Are you sure it is the macerator pump that is running or is it the vacuum generator?
Is the switch labeled and is it a 3 position switch?

Looks like it’s on or off. there are 2 push button breakers on the top of the key switch. Both are pushed in.

With the key on the macerator pump definitely runs. I ran a jumper wire from the battery + to the pressure switch and the vacuflush pump worked perfectly

lol may be using it wrong. I was told to just turn on the breaker marked head and it will turn on. I’ll check the key switch tomorrow.

NP Please report back and some pics would be great as it will help somebody in the future.

Thank you. Will do!
I have the same Irving diagram but can’t seam to trace the wire from the breaker. I’ll check the key situation

I thought the same thing but what I was hearing was the vacuflush pump building pressure.

Ok. My Bad!! I didn’t realize the switch had to be turned on for the vacuflush system to operate. I thought it was only for overboard discharge. All is good! Thank you all for the help
