1. Insert a paper clip in the engine speed detection connector
from the harness side, and attach the engine
speedometer.
NOTE
For tachometer check, use of a fluxmeter-type engine
speedometer is recommended. (Because a fluxmeter only
needs 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.
