Fuel Gauge

Use Gas Gauge Tester (J-24538-A). Disconnect feed wire from gas tank terminal and connect one test lead to wire and ground other lead. Switch tester to "EMPTY" and "FULL" positions. Fuel gauge should read same as tester. If not, proceed with following tests with ignition in "ON" position.

Gauge Never Reads Empty or

Reads Full at All Times

Check for disconnected or loose tank unit feed wire at tank. If good, check for proper connections at printed circuit.

Gauge Always Reads Empty

Disconnect tank unit feed wire. Gauge should indicate full. If not at "FULL" position, check connections to printed circuit. Check for an open in printed circuit.

Gauge Never Reads Full

Check system with Gas Gauge Tester, positioned in line between feed wire and tank terminal. If gauge reads full, fill the gas tank. Using an ohmmeter, check resistance of tank sending unit. Resistance should be between 88 and 92 ohms. If ohm reading is low, check tank mounting area for damage. If gauge does not read full, check connections to printed circuit or for an open within printed circuit.

Gauge Dead

Check feed wire voltage to tank. Voltage should read 3-4 volts. If it does not, check for open on hot side of gauge, or proper connections at printed circuit. If voltage is correct, remove and check fuel gauge.
