I'm trying to help a neighbor with a multi-item monitoring panel in the stove range hood. The range hood light
works, the water pump works, the range hood fan works, but the single switch to show the multiple system "levels" does not show any lights
. He has black water/gray water/clean water/propane levels with two battery
monitors. Each has 4 lights
showing level. None illuminate when the switch for "Levels" is thrown. All system fuses seem to be OK. The previous owner made some mods to the wiring. The way it was didn't work, neither did returning it to what looked like original connections.
There is no brandname on this panel.
Does anyone have a wiring schematic for such a panel?
Thanks in advance;
