Schematic for test circuit for fuel qty ind?

[kevin]

I received the following as an email. Can anybody help? -Kevin

Where can I get a schematic for a test circuit which I can use for testing the penny-cap fuel quantity indicating system on a Cessna skymaster.

Thank You

NOT that easy. These are capacitive guages and require a unique test box for calibrate the guages. There are not many around. Somewhere recently a SM owner replaced them with a newer alternative.

Most of the problems can be diagnosed to bad cables and connectors. try these first. check if it is one tank or both .
The systems differ greatly between p and earlier 337 or 336s. Number of tanks and if there are aux tanks. Need to start out by determining which type of aircraft.



Can of worms.. GMAS should be able to help
