Re: head problem, haha
 

Get a buddy to help you do this. Have him/her in the head to operate the switches. Go to the macerator with test light. You can get a good ground source if you remove the panel in the head behind the dash. There's a grouund block in there. With a long piece of wire (ground) and test light by the macerator have someone operate the lower switch (macerator) and check for power.
To check the pump remove the storage compartment to the right of the sink. Actually I would start here 1st. Check to see if you have power into both switches. USE THE GROUND BLOCK W/YOUR TEST LIGHT behind that panel. I'll bet it's the power source going to those switches. Test your fuses with the test light on each side. They are located under the steering wheel access.
Good luck
