Controller from '77

[Zeppelinium]

Fully functional (when removed) control panel from a 1977 Safari. Unit has the original multi-wire connector. I'm looking for a 22" outside access door from a recently salvaged Airstream. Will be glad to accept a three-way trade. If you want this panel, as is, all you need to do is find me the access door!

I have that same control panel in my 76 AS. I would like to find a more modern light setup to replace it with. You know up grade it to a newer setup, but I do not want to have to replace the sensors.

I've built a microprocessor-based display that uses the original sensors. It uses LEDs to show tank levels. This schematic (below) of the original shows how Airstream produced 4 different voltages from the sensors, so they could "read" the tank using only two wires. I'm going to do an updated display unit that has text on a 4x20 line display. The new unit will allow display of lots of other things, like fridge temperatures, etc.

An LED style is what I was thinking to that uses the original wiring set up, I was thinking with the FW pump switch built in also. But I do like the idea have having a thermometer for the fridge also. I been using a "meat" thermometer that goes down to 32 degrees in the fridge. Want to go a wireless thermometer so I don't have a thin braided wire coming out through the door seal. Another thought on the thermometer wiring was to run it through where the thermister wires run through the back of the fridge, would like to run small 12v wires through the same area to be able to plug in a small 12v hard wired fan in the fridge. That way I don't have to buy batteries for the battery powered ones.
