II. Charging system inspection1. Check battery working voltage
(1) After having driven the vehicle and in the case that 20 minutes
have not passed after having stopped the engine,turn the ignition
switch ON and turn on the electrical system (headlight,blower
motor) for 60 seconds to remove the surface charge.
(2) Turn the ignition switch OFF and turn off the electrical
systems. Then measure the battery voltage between the nega
tive and positive terminals of the battery.
Standard voltage: 12.5-12.9V at 20°C
Hint:
If the voltage is less than specification, charge the battery.
2. Check battery terminals, fuse box and fuse
(1) Check that the battery terminals are not loose or corroded.
(2) Check if fuse box and fuse for continuity.
3. Inspect drive belt
(1) Check the belt for excessive wear, frayed cords etc.
Hint:
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(2) Check that the belt fits properly in the ribbed grooves.
Hint:
Check with your hand to confirm that the belt has not slipped out
of the groove on the pulley.
4. Check alternator wiring
Check that the wiring is in good condition.Automobile Starting, Power Supply System -Charging system5-45. Listen for abnormal noises from alternator
Check that there is no abnormal noise from the alternator while the engine is running.
6. Inspect charge warning light circuit
Turn the ignition ON. Check that the charge warning light comes on. Start the engine. Check that the light
goes off.
Hint:
If the light does not work as normal, troubleshoot the charge warning light circuit.
