TERMINAL VOLTAGE CHECK CHART

NOTE: *1: The average voltage through an analog voltmeter is shown in the table (because the average voltage is too stable to be shown on a digital voltmeter).

NOTE: *2: Vehicles for Canada, the headlight, taillight, etc. remain lit even when the lighting switch is in "OFF" position but this is no problem for checks.
