2011 Ballast tank switches are dead

2011 X25 Does anyone happen to how the ballast tank switches are wired? Mine are no longer lit or functional. Tower Light switch is lit and functional. Iíve checked every fuse I can find and pried open the Jabsco control box. I believe I moved one of the switches to Fill while underway. Do relays actually fail like fuses? Thanks for any assistance.

MC doesn't supply electrical schematics of course .
But yes relays do fail, just not all at once.
if the switches don't light I doubt its any of the relays. Many times the ground will fall off or have an oxidized connection and thus nothing will work.
The first thing I would do is verify a wire hasn't fallen off the back of the fuse holder / breaker.
Same on the switch panel. This thread has some really good info on the subject. Grounds are no fun to find because there is no beaker to rest anything.

In the diagram I think your issue is the wiring at the top left. Either one of them is off, you wont pull in the relay coil to energize the relay and send 12v to the pump motor via the heavy Red/Black wiring.

I have an update - I have tracked the source of the intermittent switch problem - the 50 amp fuse holder buried in a nest of wiring harnesses next to the transmission. I have not solved the problem but I can recreate the problem and bring them back to life by pushing the fuse in tighter.

Disconnect ground from your battery(s), then open that fuse holder up and take pics.

Don’t open it up without the battery groung(s) being disconnected. My guess would be that you have corroded contacts in there.
