ON−VEHICLE INSPECTION
CAUTION:
S
Check that the battery cables are connected to the
correct terminals.
S
Disconnect the battery cables when the battery is giv-
en a quick charge.
S
Do not perform tests with a high voltage insulation re-
sistance tester.
S
Never disconnect the battery while the engine is run-
ning.
1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell (Maintenance−
Free Battery).
If under the lower level, replace the battery (or add distilled wa-
ter if possible) and check the charging system.
(b) Check the electrolyte quantity of each cell (Except Main-
tenance−Free Battery).
If under the lower level, add distilled water.
2. CHECK BATTERY SPECIFIC GRAVITY
(Except Maintenance−Free Battery)
(a) Check the specific gravity of each cell.
Standard specific gravity: 1.25 to 1.29 at 20_C (68_F)
HINT:
If the specific gravity is less than specification, charge the bat-
tery.
A01259
3. CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (−)
A01260
and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20_C (68_F)
HINT:
If the voltage is less than specification, charge the battery.
