Sigma-Tek engine cluster gauges

Recommended Posts

The Sigma-Tek engine cluster gauges have been removed from my 1990 J for installation of an EDM900. Transducers included.

****Oil Pressure transducer is sold******

Condition:

Fuel quantity, CHT and amps/volts all work well.

Fuel pressure on rare occasion will stick at zero after engine start, but a tap on the gauge will get it to register and it works fine after that.

Oil pressure also will stick at zero after engine start but will spring to life with a tap. It seems to happen any time the airplane has not run for a week or more.

Oil temp gauge needs overhaul, I wouldn't trust it.

Make me an offer...
