Be sure the battery is sufficiently charged.

Raise the hoist to full height and remove the engine undercover.

Hook up the ammeter, 0−400 A, to the starter subharness.

Lower the hoist.

Hook up the voltmeter, 0−20 V (accurate within 0.1 V), to T101.

Start the engine. Hold the engine at 3,000 rpm (min ⁻¹ ) with no load shift lever in Neutral, until the radiator fan comes on then let it idle.

Raise the engine speed to 2,000 rpm (min ⁻¹ ) and hold it there.

Turn the headlights (high beam) on, and measure voltage at the under-hood fuse/relay box terminal.

Read the amperage at 13.5 V.

NOTE: Adjust the voltage by turning the blower motor, rear window defogger, brake lights, and etc. ON.
