INSPECT CHARGING CIRCUIT WITH LOAD
(a)
With the engine running at 2,000 rpm, turn on the high beam headlights and place the heater blower
switch at "HI".
(b)
Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than standard amperage, repair the alternator.
HINT:
If the battery is fully charged, the indication will sometimes be less than standard amperage.
