My shop manual says to measure PURPLE/PINK and BLACK at the gauge plug. I unplug the connector and place multimeter leads on the specified wires (pin 1 and 3). I press the start/stop button... the relay clicks... I get 11.90V. I plug the connector back into the gauge... no reading on the gauge whatsoever.
I remove the gauge and take it to the bench. When I run 12.5V from a bench battery straight to the gauge on those mating pins, I get no fuel reading, but the OIL lamp lights up red. Is this behavior expected? If not, can someone verify the correct pinout for pins 1 and 3 are indeed PURPLE/PINK and BLACK (not necessarily in that order.)
I just replaced the entire baffle assy tonight. I'm getting 60.8 Ohm reading.
The gauge backlight works.
