Question original tank sensors

where can I find original/original style sensors for the fresh water tank so I can still use the original readouts on the control panel? PO threw out the original tank.

The tank sensors in my tanks are solely terminations of electrically conducting wires. There is one live sensor at the bottom of the tank, IIRC, and 4 grounds at the various levels; 1/4, 1/2, 3/4, and Full. The liquid just completes the circuit between the live and the various grounds, and the lights illuminate in the panel. If, for example, the tank is 1/2 full, the Empty, 1/4 and 1/2 lights all illuminate. If yours were the same, the sensors are very simple, and I ordered replacement sensors from my local Airstream dealer for a few dollars. You would probably need to order them for a later trailer, like mine, rather than yours, as any catalogue would probably list yours as "unobtainable". They are designed to be glued into a hole drilled in the tank, and they are in the corner side wall near the outlet. They are very difficult to keep clean and operational in a black tank.

sensors

I tried connecting the wires together, and they did infact light up the display, however I need to investigate more because it only lit up 0/0 1/4 and 1/2 and there doesn't appear to be power for lights for the 3/4 and full so I need to look inside. I definately need to rebuild for find replacement spring loaded switches, as they take work to get them to make contact sometimes.

A good place to start looking is Farnell's catalogue, which offers 9,900 types of switch here:
Farnell Export=

Happy hunting!
