Colyn,


I have the same problem. I've been looking at the power to the converters,
checked the securing of all the connections, etc, but I've found nothing so
far. Are you using the 12 vdc source out of the GRT to power the converters
or "aircraft power"? It appears to be the common element. Since both of
these indications go to zero at the same time, but nothing else displayed on
the engine monitor changes, that could be a plausable cause. I'd love to
know if you find something

Subject: [LML] flaky fuel indications


long as we're talking electrical problems:


I have ei capacitive fuel probes with princeton converters and a grt engine
monitor (like the chelton engine monitor).

My fuel level on both tanks intermittently shows zero when flying but never
on the ground.


Any idea where to look?
