My port fuel flow reads but my STBD doesn’t. I have investigated most of the system including the gauge and the sensor, no joy. Re-spliced all wires, dielectric, checked needles, nothing. When I turn both engine on, both needles move up and down but only port will read, stbd stays down? Any advice?
I tried to source replacement parts for my Flowscans but they were NLA if I recall.
Ended up tearing them out and instead use the internal counters that the Honda 225’s have and push out over NMEA. Then paired it with a little Honda/Simrad fuel computer. Much cleaner setup, but was quite a big project.
