Tachometer: Testing and Inspection

Tacometer Inspection: Step (1):

1. Insert paper clip into the engine revolution speed detection terminal provided in the engine compartment, and connect the engine tachometer to the inserted paper clip.
NOTE:
For tachometer inspection, use of an inductive type engine tachometer is recommended. (Because an inductive type only needs to be clipped to the high tension cable.)

Tachometer Inspection: Step (2):

2. Connect the engine tachometer and compare the engine tachometer and tachometer readings. Replace tachometer if difference is excessive.
