INSTRUMENT CLUSTER REPAIRTachometer
NOTE: The tach needle will not return to zero if the engine is turned off while the engine speed is 4000 rpm or higher when the ROOM fuse is not installed. The tach needle will continue to rotate clockwise until it rests on the wrong side of the stopper pin. If a customer complains of this concern, inspect the ROOM fuse and if necessary, repair according to the following steps.
1. Verify the concern.
2. Verify that the ROOM fuse is installed.
3. Start the engine and increase the engine speed to approximately 5500 rpm or until the needle begins to move away from the stopper pin (counterclockwise).
4. Decrease the engine speed to idle and turn the ignition switch to LOCK position.
5. Verify that the needle returns to zero.
6. If the needle does not return to zero, remove the lens and carefully move the needle by hand.
