Smartcraft Gauge Faults
Posted: Wed Aug 03, 2022 1:41 pm
On twin Optimax 150-HP engines the Smartcraft tachometer gauge for the Port engine seems to be working well with no faults, however for the last year,the Smartcraft tachometer gauge for the Starboard engine has had miscellaneous faults:
The oil level fault wasn't present last year. This year while de-winterizing and before launching, I topped off both engines' remote oil tanks. I filled the tanks to the top of the filler neck and there was an audible GLUG-GLUG GLUG from air gurgling to the top of the filler neck. Apparently I shouldn't have filled to the top of the neck, but what's done is done.
After starting the engines on a hose adaptor, the Starboard engine Smartcraft tachometer gauge showed an oil level fault.
A "center gauge " reads 0.0.
I followed the bleed procedures for the under-cowling oil tank three times, but got no remedy.
I still get the OIL LEVEL FAULT on the Starboard engine Smartcraft tachometer gauge and also on a "center gauge " with a reading of 0.0 for Starboard [oil tank] level; reading for Port [oil tank] level is 2.5 gallons.
Since there's a specific gallon reading, I'm assuming that the oil tanks have a level sensor.
There is a noticeable amount of pressure in the oil tank when unscrewing the cap after operation. I assume this is normal, but maybe not.
Assuming there are sensors and connectors for the tank level for the oil tanks,
Q1: should I be troubleshooting a sensor?
Q2: should I be troubleshooting a connector?
Q3: is the remedy to recalibrate the Smartcraft gauges?
Q4: what is the procedure to recalibrate a Smartcraft gauge?
