Question

The fuel gauge in my 1980 Corvette always reads too full.
The mylar printed circuit board has 3 connector pads for "Low Fuel"
bulb socket. I'm not sure about this because the socket only had 2 conectors
for bulb. Is the bulb a resistance for fuel gage ?.

The gage reads just beyond the reserve marks when I ground the wire at the gas tank.
This is the same amount above full when I hook a 90 ohm [full] resistor to wire at tank.
Hope this helps.
ThanksTerry
