1. Check that the battery cables are connected to the correct terminals.
2. Disconnect the battery cables when the battery is given a quick charge.
3. Do not do these tests with a high voltage insulation resistance tester.
4. Never disconnect the battery while the engine is running.

ON±VEHICLE INSPECTION
1. CHECK BATTERY ELECTROYTE LEVEL AND VOLTAGE
(a) Check the electrolyte quantity of each cell.
Maintenance±Free Battery:
If under the lower level, replace the battery (or add distilled
water if possible.). Need to check the charging system.
Except Maintenance±Free Battery:
If under the lower level, add distilled water.
(b) Except Maintenance±Free Battery:
Check the specific gravity of each cell.
Standard specific gravity:
1.27±1.29 at 205C (685F)
If the specific gravity is less than specification, charge the
battery.
(c) Maintenance±Free Battery:
Measure the battery voltage between the negative (±) and
positive (+) terminals of the battery.
Standard voltage:
12.7±12.9 V at 205C (685F)
HINT:
wBefore measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight,
blower motor, rear defogger etc.) for 60 seconds to
remove the surface charge.
wIf the vehicle has been running, wait 5 minutes or more
after the vehicle stops before measuring the battery
voltage.
If the voltage is less than specification, charge the battery.
HINT: Check the indicator as shown in the illustration.
