Fuel Gauge
NOTE:
The fuel gauge is part of the fuel/temperature gauge assembly. Neither of these gauges is serviceable separately. If either gauge malfunctions, assembly must be replaced.
- Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Remove fuel indicator module from back of instrument cluster. See FUEL INDICATOR MODULE under REMOVAL & INSTALLATION.
- Using a jumper, connect fuel gauge "B" terminal to battery voltage, and fuel gauge "G" terminal to ground. See Fig 1 .
- Connect one lead of Rotunda Instrument Gauge System Tester (014-R1063), or equivalent, to "S" terminal of fuel gauge and other lead to "G" terminal of fuel gauge.
- Adjust instrument gauge tester to resistances shown in the FUEL GAUGE RESISTANCE table.
- If fuel gauge does not operate as specified, replace fuel gauge. If fuel gauge is okay, test fuel gauge indicator module and fuel gauge sending unit.
FUEL GAUGE RESISTANCE
