illuminated hot water tank switch (update)
New to Me, 2006 HR Admiral, the AC switch for the hot water tank does not illuminate when turned on. It is working as we get hot water and I can see the amp draw jump on the control panel when turned ...

Three wires for a lighted switch to show it is on is common.
One wire from the power source (AC distribution panel) to one side of the switch.
Second wire from the other side of the switch to the controlled device (the water heater element).
Third wire from the light to ground or neutral (in this case neutral).
The other side of the light would be connected internally to the load side of the switch.
The first two wires would be sized for the load (I.e. the amps required for the heater element).
The other wire would only need to carry the light bulb current.
Only surprise is that one wire is green. I would have expected two large black and a small white. I am guessing the large green wire goes to the heating element?
Do the other lights work correctly?
(This is assuming the switch controls the heater directly rather than thru a relay.)
