Grob 115 Fuel Gauge - defaults to "FULL" !
After a recent incident, I discovered that the fuel gauge or sender on a Grob 115 was shorting out, the result of which is that the needle points to "full" (in fact, the tank was empty). It is impossible to visually check, or dip, the fuel tank, which is centrally located.
Does anyone know of any modification for the Grob which allows either a visual check on fuel, or a check on the fuel gauge functionality? Would it be possible to wire the gauge to default to "empty" if it was shorted out?
