Fuel Gauge
NOTE:
Fuel gauge is part of the fuel/temperature gauge assembly. Neither of these gauges is serviceable separately. If either gauge malfunctions, entire 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 terminal "B" to battery voltage and fuel gauge terminal "G" to ground. See Fig 1. Connect one lead of Rotunda Instrument Gauge System Tester (014-R1063), or equivalent, to terminal "S" of fuel gauge and other lead to terminal "G" of fuel gauge.
- Adjust instrument gauge tester to appropriate resistances an observe fuel gauge. See 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
| Fuel Gauge | Resistance (Ohms) |
|---|---|
| F | 130-145 |
| 3/4 | 95-110 |
| 1/2 | 65-75 |
| 1/4 | 50-55 |
