Temperature Gauge
- If temperature gauge needle does not move at all, check for blown fuse or loose harness connector. If fuel gauge is also inoperative, check instrument voltage regulator.
- Disconnect sending unit connector wire. Connect ohmmeter to connector wire and ground.
- Use TEMPERATURE GAUGE RESISTANCE
table to check gauge reading. Turn ignition switch to "ON" position and ensure needle position corresponds to resistance measurement. SeeFig 1
.
- Allow 2 minutes for needle to stabilize. Allowable limit of needle deflection is twice the width of the needle. If gauge readings are not as shown in tables, replace sending unit.
