TEST
1. Be sure that voltmeter reading is identified with battery
voltage.
If voltmeter reading is 0V, it means short circuit of wire
between
B terminal and the battery (-) terminal, fusible
link cut off or ground fault.
2. Turn the headlight ON and start the engine.
3. With the engine running at 2,500 rpm, turn ON the high beam
headlights, place the heater blower switch at HIGH mea-
sure the maximum output current using a ammeter.

This test should be done as soon as possible to mea-
sure the exact maximum current because output
current drops rapidly after starting the engine.
