Anybody can tell me the source of these power wires? I thought they would go to the Macerator breaker, unless there is a switch somewhere. I cannot get coninunity from the Macerator to the breaker
 
There could be a safety switch on your seacock or Y valve... makes the circuit up only when open.
 
On my '95 300 there was a switch in the panel that you had to depress and hold to engage the circuit to pump the holding tank overboard. It was labelled "discharge". Post a picture, I also had an electric head with macerator right at the toilet bowl. Which are you referring to overboard discharge in bilge or head macerator?
 
Most of older boats didnt have "safety" switch on mascerator discharge seacock handle. Usually there were mascerator breaker on electrical panel and momentarily switch installed in the head. That switch often was in form of ignition switch. You had to keep key in start position and listen to mascerator changing sound. You dont want to run it dry for too long. You need to remember to open discharge seacock and you may also have Y-valve. It need to be switch to discharge position (not pump out). Failing to open a seacock or Y-valve and you taking a risk of blowing out hose and stinky bilge.
 
Macerator is aft of holding tank with overboard seacock, no electrical safety switches to Y-valve or seacock, no switches in Head, only breaker in panel
 
Hmm. You are missing something. There has to be dedicated switch (likely momentarily) for mascerator. I have never seen sea ray just with breaker and I worked on those for over 20 yrs. Do you care to post picture of 12V panel and any panels in head?
