| BATTERY DIAGNOSTIC TEST
(2) |
| 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 worn 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 from
battery. |
|
LOAD
TEST
| 1. |
Perform the following steps to complete the
load test procedure for maintenance free
batteries. |
| 2. |
Connect the load tester clamps to the
terminals and proceed with the test as follow:
| (1) |
If the battery has been on charge,
remove the surface charge by connecting a 300ampere load for
15 seconds. |
| (2) |
Connect the voltmeter and apply the
specified load. |
| (3) |
Read the voltage after the load has
been applied for 15 seconds. |
| (5) |
Compare the voltage reading with the
minimum and replace the battery if battery test voltage is
below that shown in the voltage
table. |
