− CHARGING SYSTEM
Measure the battery voltage between the negative (−)
and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20°C (68°F)
CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
Check that the battery terminals are not loose or cor-
roded.
Check the fusible link and fuses for continuity.
INSPECT DRIVE BELT

tensioner has a left−hand thread.
Check the belt tensioner operation.
S
Check that the belt tensioner moves downward
when the drive belt is pressed down at the points in-
dicated in the illustration with approx. 98 N (10 kgf,
22.0 lbf) of force.
S
Check the alignment of the belt tensioner pulley to
make sure the drive belt has not slipped off the
pulley.
