A few years ago I purchased a nice flying RV-6A. The plane has been a joy and very trouble free. However, about a year ago BOTH fuel level gauges started acting ?screwy?. These are standard Van?s gauges and sender units. My big problem is I cannot get to the back of the gauges or even start to replace them without completely or at least partially pulling the instrument panel which will be a LOT of work. I am considering just living with this for another year since my fuel flow computer is very accurate. But I cannot imagine what is wrong other than both gauges have just gone bad. I am open to advice. Here?s what I am seeing:
RIGHT TANK:
Tank drained indicates zero with a measurement of 247 ohms across the sender.
Tank full indicates 12 gal with a measurement of 31 ohms across the sender.
With sender main wire disconnected, gauge indicates zero.
With sender main wire grounded gauge indicates 12 gal.
LEFT TANK
Tank drained indicates 5 gal with a measurement of 259 ohms across the sender.
Tank full indicates pegged, (gauge full scale) with a measurement of 34 ohms across the sender.
With sender main wire disconnected, gauge reads 5 gal.
With sender main wire grounded, gauge is pegged.
