Temperature Gauge
NOTE:
After changing checker resistance value, allow 2 minutes for needle to stabilize. Allowable limit of needle deflection is twice width of needle.
- Disconnect temperature gauge sending unit connector. Connect Red wire lead of Checker (49-0839-285) to sending unit connector terminal and Black wire lead to ground.
- Turn ignition on. Set checker to specified resistance value. See TEMPERATURE GAUGE RESISTANCE . If gauge needle rests at specified position for each resistance value setting, replace sending unit. If gauge needle does not rest at specified position, check wiring. If wiring is okay, replace gauge.
