Cleaning
|
1. |
Make sure the ignition switch and all accessories are in the OFF
position.
|
|
2. |
Disconnect the battery cables (negative first).
|
|
3. |
Remove the battery from the vehicle.
|
Care should be taken in the event the battery case is
cracked or leaking, to protect your skin from the electrolyte.
Heavy rubber gloves (not the household type) should be
wore when removing the battery.
|
|
|
4. |
Inspect the battery tray for damage caused by the loss of electrolyte.
If acid damage is present, it will be necessary to clean the area with
a solution of clean warm water and baking soda. Scrub the area with
a stiff brush and wipe off with a cloth moistened with baking soda and
water.
|
|
5. |
Clean the top of the battery with the same solution as described
above.
|
|
6. |
Inspect the battery case and cover for cracks. If cracks are present,
the battery must be replaced.
|
|
7. |
Clean the battery posts with a suitable battery post tool.
|
|
8. |
Clean the inside surface of the terminal clamps with a suitable
battery cleaning tool. Replace damaged or frayed cables and broken terminal
clamps.
|
|
9. |
Install the battery in the vehicle.
|
|
10. |
Connect the cable terminals to the battery post, making sure tops
of the terminals are flush with the tops of the posts.
|
|
11. |
Tighten the terminal nuts securely.
|
|
12. |
Coat all connections with light mineral grease after tightening.
|
When batteries are being charged, an explosive gas forms
beneath the cover of each cell. Do not smoke near batteries
being charged or which have recently been charged. Do not break
live circuit at the terminals of batteries being charged.
A spark will occur when the circuit is broken. Keep open
flames away form battery.

Inspection
Battery Diagnostic Flow
Vehicle parasitic current inspection
|
1. |
Turn the all electric devices OFF, and then turn the ignition
switch OFF.
|
|
2. |
Close all doors except the engine hood, and then lock all doors.
|
(1) |
Disconnect the hood switch connector.
|
|
(3) |
Close the doors or remove the door switches.
|
|
|
3. |
Wait a few minutes until the vehicle’s electrical systems go to
sleep mode.
|
For an accurate measurement of a vehicle parasitic current,
all electriacl systems should go to sleep mode. (It takes at
least one hour or at most one day.) However, an approximate
vehicle parasitic current can be measured after 10~20 minutes.
|
|
|
4. |
Connect an ammeter in series between the battery (-) terminal
and the ground cable, and then disconnect the clamp from the battery
(-) terminal slowly.
|
Be careful that the lead wires of an ammeter do not come
off from the battery (-) terminal and the ground cable to prevent
the battery from being reset. In case the battery is reset,
connect the battery cable again, and then start the engine or
turn the ignition switch ON for more than 10 sec. Repeat the
procedure from No. 1.
To prevent the battery from being reset during the inspection,
| 1) |
Connect a jump cable between the battery (-) terminal
and the ground cable.
|
| 2) |
Disconnect the ground cable from the battery (-)
terminal.
|
| 3) |
Connect an ammeter between the battery (-) terminal
and the ground cable.
|
| 4) |
After disconnecting the jump cable, read the current
value of the ammeter.
|
|
|
|
5. |
Read the current value of the ammeter.
| A. |
If the parasitic current is over the limit value, search
for abnormal circuit by removing a fuse one by one and checking
the parasitic current.
|
| B. |
Check the parasitic current again, and search for suspected
unit by removing a unit connected with the abnormal circuit
one by one.
|
Limit value (after 10~20 min.)
: Below 50mA
