BATTERY DIAGNOSTIC TEST (1)
CHECKING FLOW
Step 1: Visual inspection
Check for obvious damage such as a cracked or
broken terminal and case or cover that could permit
leakage of electrolyte.
Determine the cause of damage and correct as
needed.
Clan any corrosion with as solution of baking soda
and water.
Replace battery
Step 2: Measure battery voltage after romoving
theterminals
Check the voltage after at least one hour in case of
recharging the battery, and the recharging should be
made in accordance with the charging instructions.
Charge battery
Step 3: Load test
Perform an electrical load using the appropriate load
test amperage specifications for the 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 connect 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.
4)
Disconnect the load.
5)
Compare the voltage reading with the minimum
and replace the battery if battery test voltage is
below that shown in the voltage table.

NOTE
-
If the voltage is greater shown in the table, the
battery is good.
-
If the voltage is less than shown in the table, re-
place the battery.
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.
CAUTION
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, mak-
ing 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.
CAUTION
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 cir-
cuit at the terminals of batteries being charged.
A spark will occur when the circuit is broken.
Keep open flames away form battery.
