Water indicator light is always on green

[Californio]

As the title says. Even empty, the kitchen water tank light is on green. This is an 87 Syncro, which has the old style tank sensors, not the one in the the cap.

The Bentley doesn't cover this wiring--in fact, 97-32b mistakenly shows early models of campers having the later in-cap sensor.

Any one have a diagram of the early sensor setup? I can't figure it out.

I cleaned the inside part of the terminals with 400 grit but no change. I can clean up the outside spade connectors but I'd be surprised if that made a difference.

What I can't tell is why, if the tank is empty, the green light is always on. Something weird. It makes no difference if the spade connectors at the tank are on or off, green light stays on.

I think the sensors in the tank just complete a path to ground, right?

Long shot, but it’s not the bottomed green LED for the fridge is it?

Also, is the pump off? I think my my water level turns green when I turn the pump on.

[Californio]

No, it's the top one, not the fridge propane-on light. Pump functions normally and the level light stays green with it on or off.

Interesting why yours would turn green when you use the pump, never heard of that one.

Sounds like there is a short in the wiring to the display causing the light to stay on. Try tracing the wiring harness from the display to the tank.

I would be checking the ground at the 'little black box' that hides the connections from the tank 'sensors' to the loom at the front of the tank.

Yes, the only thing I can think of is that the green wire to the panel is somehow grounding out between the tank sensor and the light. I'll post if and when I find what it is.
