•
Turn the ignition switch ON and push the lanyard k ey un-
der the stop button.
•
Pushing the start button, run the engine 5 ∼ 6 seconds at
idling to measure the sensor output voltage.
○
Wait 15 seconds before using the starter again.

Standard: about 3 ∼ 4 V at 20°C (68°F)
NOTE
○
The output voltage changes according to the oil temper-
ature in the engine.
