Still trying to get these fuel gauges to work. The sender units are
10-76 ohms and the ROCHESTER FUEL LEVEL Indicators are 0 - 90 ohms
also if I apply 12v to the sen terminal and put a 45 ohm resister
inline to ground on the center terminal [the center terminal has a
metal plate which extends to around the light bulb hole ] it reads
1/2 way on the gauge which appears to be the correct value.Still
not sure what the ign terminal is used for then !!!! Cheers Alan

Did you try hooking 12v to IGN, center to ground
and SEN to ground through a 45 ohm resistor? The
meanings of the markings are quite clear. Applying
12v to a SEN terminal will yield meaningless results
and may damage the instrument.
