2. BATTERY ANALYSIS
OPERATION
OCBLT-100
Check the battery terminal clamps are correctly connected to the lead
acid battery. Twist the clamps slightly to ensure a good connection.
6V Battery Analysis
1. Confirm battery voltage is in the
green “OK” area of the 6V Range
area. If it is not in the OK range,
disconnect the battery and recharge
before retesting.
2. Press and hold the load switch in the
ON (-) position for a maximum of 10
seconds while reading the meter. The
needle should remain in the green area,
if it does not, the battery is weak or
bad.
WARNING!
TO PREVENT OVERHEATING, ALLOW
UNIT TO COOL FOR 5 MINUTES BEFORE DEPRESSING
THE LOAD SWITCH AGAIN IF FURTHER TESTING IS
REQUIRED.
12V Battery Analysis
1. Confirm battery Cold Cranking
Amps (CCA) on the meter that
matches the CCA rating of the
battery being tested.
2. Press and hold the load switch
ON (-) position for a maximum of 10
seconds while reading the meter. The
needle should indicate the approximate
capacity (for 12V batteries
200-1000CCA), refer to
Battery
Analysis
table in this manual or on the
label.
WARNING!
TO PREVENT OVERHEATING, ALLOW
UNIT TO COOL FOR 5 MINUTES BEFORE DEPRESSING
THE LOAD SWITCH AGAIN IF FURTHER TESTING IS
REQUIRED.
Testing the Charging System
With the battery terminal clamps correctly connected to your vehicles
Lead Acid Battery and all electronic accessories off.
1. Start the engine and accelerate to 1200 - 1500 rpm.
2. Confirm reading is in the green
“OK” position in the Charging Test
Range area.
3. Turn on the headlights and fan
motor on high, the meter should
remain in the green “OK” area.
4. If the reading is in the red area or outside the charging system zone,
the alternator may be defective.
WARNING!
DO NOT PRESS THE LOAD SWITCH DURING
THIS TEST.
Testing the Vehicles Starter Motor
This will identify excessive starter current draw, which makes starting
difficult and potentially shortens battery life. It is best to load test
the battery before starter motor test to ensure the battery is in good
condition. If the battery tests either weak or bad, this test cannot be
performed.
Note:
The vehicles engine must be off and at normal operating
temperature.
WARNING!
DO NOT PRESS THE LOAD SWITCH DURING
THIS TEST.
1. Perform a load voltage test to confirm battery’s state of charge
reading is in the green “OK position and note the exact voltage.
2. Using the load voltage obtained in step 1, refer to the meter to select
the minimum cranking voltage. Apply next higher minimum crank
volts for engines with less than 200 CID.
- For example, if the load voltage is 11.00, use 10.2 for the minimum
cranking volts instead of 9.7.
3. The vehicles ignition must be disabled so the engine will not start.
(Refer to the vehicle’s instruction manual or contact a automotive
professional technician for advice). The test works best if the starter
cranks for 2 to 5 seconds.
4. With an assistant cranking the engine, view the meter voltage reading.
5. If the cranking volts during the test is less than the minimum cranking
volts selected from the table, the starter current draw is excessive.
If the starter cranks slowly, check for high resistance or poor
connections.
WARNING!
ENSURE LOAD TESTER AND CABLES ARE
CLEAR OF ANY MOVING PARTS.
