The head does not work. I've checked the fuses, had the holding tank pumped out, verified that the raw water pump is working and that the macerator will work if I apply power directly to it. Nothing works if I push any of the buttons on the head control panel, like flush, fill, empty , or quick flush.

Can you remove the panel to check for voltage at the feed?

I'm not sure where to check.
Marine Mechanic: Boat Doc, Boat Enthusiast replied 4 months ago

Can you tell me what model head system you have? Any markings? Possibly a picture of the panel?

It's a 38110 holding tank with a jabsco delux flush electric head

Y​ou should have a small black control box mounted near the toilet. There is a red and a black lead coming into it. You need to check to see if there is 12 volts on those leads first.
