damp or wet location.

WARNING! People with pacemakers should consult their physician(s) before
using this product. Operation of electrical equipment in close proximity to a
heart pacemaker could cause interference or failure of the pacemaker.

SPECIFIC SAFETY RULES FOR THE BATTERY TESTER

1. When connecting the Battery Cables to the battery, av oid creating sparks (always
connect and disconnect clamps exactly as described in rule number 2, below,
and on page 4), especially when the battery is being charged. Explosive gases
are created during charging. Sparking could also damage the vehicle electrical
system.

2. Be certain of the test battery polarity before connecting the test Cable Clamps .
The red Cable Clamp (A) goes to the positive terminal of the battery . The b lack
Cable Clamp (B) goes to the negative terminal of the battery .

3. When placing the Battery Tester in the vehicle (on the frame, engine, or f ender),
take special care that the metal housing of the Battery Tester does not come in
contact with either terminal of the battery or other electrical connections.

4. Do not drop the Battery Tester as it may affect proper operation.

5. Do not smoke or have open flames near the battery.

SKU 90893 Page 3

6. Rev ersing Battery Tester Cable Clamps on the battery will damage the tester.

7. Do not connect the Battery T ester to the battery while the battery is being charged.
T urn the engine off before connecting.

8. Do not touch the cooling vents on the Battery Tester immediately after testing
the battery . The y become very hot.

OPERATING INSTRUCTIONS

Testing the Battery

Undercharged lead-acid batteries will freeze during cold weather .

NEVER TEST OR CHARGE A FROZEN B A TTER Y .

1. To help ensure a good connection, clean batter y terminals with a solution of
baking soda and water, and wipe the battery terminals with a cloth to remove
any dirt and grease.

2. Connect the red (positive) Cable Clamp (A) to the positive terminal (+) on the 6
or 12 V lead-acid battery . (See photo abov e.)

3. Connect the black (negative) Cable Clamp (B) to the negative terminal (–) on the
battery . Turn clamps slightly to ensure a good connection.

4. With the clamps connected, the tester’s gauge will show the battery’s current
charge. If it is less than 12 V on a 12 V battery (or 6 V on a 6 V battery),
disconnect the battery and recharge before testing. If recharging will not bring
the reading above the appropriate voltage (noted above), the battery is defective.
If it shows no reading, verify that the tester is connected properly. If the tester
is connected properly , the battery is defectiv e .

SKU 90893 Page 4

5. Press (and hold) the Toggle Switch (C) for at least 5 seconds to simulate an
actual load on the battery .

6. View the Meter Display (D) and read the battery condition. Refer to the “Battery
Condition Analysis” section below .

7. Release the T oggle Switch (C) and remo ve the Cable Clamps from the battery.

Testing the Charging System

Note: The engine should be at normal operating temperature during this test.

1. Connect the Cable Clamps (A, B) to the battery as previously described.

2. Outside, or in a well ventilated area, start the vehicle engine and run at fast idle
speed. Ne v er start and run the vehicle’s engine in a closed garage .

Av oid Carbon Monoxide poisoning. This gas comes
from the vehicle exhaust and is colorless and odorless. It can
cause serious injury or death if inhaled. Never run the vehicle’ s
engine inside a garage or any other enclosed space.

3. View the Meter Display (D) and read the charging system condition (far right on
the gauge). Ref er to the “Battery Condition Analysis” section below .

Caution: DO NO T press the T oggle Switc h (C) during this test.

Testing the Starter

Note: The engine should be at normal operating temperature and the battery

should be fully charged before doing this test.

1. Connect the Cable Clamps (A, B) to the battery as previously described.

2. Disable the ignition so the engine will not start. (Ref er to your vehicle’ s manual.)

3. Have an assistant crank the engine. Note the voltage reading during cranking.

3. View the Meter Display (D) and read the voltage. A reading of 9 volts or less
indicates excessive current dr aw f or a 12 V system. This ma y be due to a poor
connection, a failing starter, or a battery of insufficient size for the motor.

Caution: DO NO T press the T oggle Switc h (C) during this test.

INSPECTION, MAINTENANCE, AND CLEANING

1. Periodically recheck all n uts, bolts, and screws for tightness.

2. Store in a clean and dry location.

3. Clean the outside of the unit with a damp cloth. Never use solvents to clean any
part of this tool. Use compressed air to blo w out debris from the load vents .

4. After each use, clean the Cable Clamps of any possible battery electrolyte.
Apply a thin coat of silicon grease to prevent corrosion.
