Fuel Gauge Errors
Posted: Thu May 18, 2017 4:28 pm
has anyone else checked the fuel quantity before engine start and after?
I see a 2 gallon reduction in fuel quantity with the engine running for both tanks.
it seems to be voltage related, if I shut the alternator off the system voltage reduces and the fuel quantity goes back up.
the resistive gauges are wired to the HXr analog inputs using the internal pull up resistor.
Any ideas?
