Correct - only the breaker on the main 12V panel and the breaker in the head.While on the topic of electricity to the vacuflush, i need to verify that there is only the switch in the 12v panel, and the breakers in the head itself. There is no othe r fuse in the system? I have power to the panel in the head, and I can run the overboard discharge pump, but the vacuum generator motor is not running. I am replacing the vacuum switch next, but want to be sure that there is no other switch or fuse in the system.
The vac switches do get lazy over time, but I sure wouldn't replace without diagnosing, first. Do you have power at the vac switch? Leaving the vac switch?
