Tachometer: Testing and Inspection
TACHOMETER CHECK
1. Insert a paper clip in the capacitor connector from the harness side, and attach the engine speedometer.
NOTE: For tachometer inspection, use an inductive-type engine speedometer. (Inductive tachometers only need to be clipped to the high tension cable.)
2. Compare the readings of the engine speedometer and the tachometer at every engine speed, and check if the variations are within the standard values.
Standard value:
700 r/min: ±100 r/min
3,000 r/min: ±150 r/min
5,000 r/min: ±250 r/min
6,000 r/min: ±300 r/min
