Charging Current Inspection
CAUTION:
Before inspection, perform the following.
- Check drive belt. Refer to Inspection .
- Check electrical lines to battery, alternator, starter motor and on the ground point for the battery in the engine compartment for tight seating and check for a perfect condition.
- Check ground cable between engine and body for tight seating and proper condition.
- Connect volt/amp(s) tester (A) with current clamp (B) as shown in the figure.
: Alternator
: Battery
- Start engine.
- Check charging current when apply load to battery using volt/amp(s) tester at specified engine speed.CAUTION:
- Alter load resistance long enough until the maximum charging current is achieved.
- Charging voltage must not drop below 12.7V while this inspection.
Charging current
: Refer to Alternator .
- If charging current is below the specified value, check alternator diodes.
