Safety Precautions
When Working on Vehicles
Always wear approved eye protection.
Always operate the vehicle in a well-ventilated area. Do not inhale exhaust
gasesthey are very poisonous!
Never smoke or have open flames near vehicle. Vapors from gasoline and charg-
ing batteries are highly flammable and explosive. Always keep a fire extinguisher
suitable for gasoline/electrical/chemical fires handy.
Always keep yourself, tools, and test equipment away from all moving or hot en-
gine parts.
Never lay tools on vehicle battery. You may short the terminals together, causing
harm to yourself, the tools, or the battery.
Always turn ignition key OFF when connecting or disconnecting electrical compo-
nents, unless otherwise instructed.
Keep away from engine cooling fan. On some vehicles, the fan may start up unex-
pectedly.
Never leave vehicle unattended while running tests.
Always make sure the vehicle is in Park (automatic transmission) or Neutral
(manual transmission) and that the parking brake is firmly set. Block the drive
wheels.
Always follow vehicle manufacturers warnings, cautions, and service procedures.
Additional Precautions When Testing
Discharged batteries will freeze. Store batteries above 32°F (0°C) or maintain
batteries in a charged condition.
The Battery Load Tester becomes hot during test. Allow it to cool between tests.
The display begins dimming when the tester is not allowed to cool. Repeated use
in the overheated condition can damage the testers electronics.
Lead-acid batteries contain sulfuric-acid as the electrolyte. The electrolyte is ex-
tremely corrosive and evolves oxygen and hydrogen during charging, which can
ignite and cause an explosion. Have ventilation and keep flames and sparks away
from charging battery. Follow the manufacturers charging procedures.
If electrolyte contacts skin, immediately rinse with water. If electrolyte contacts
eyes, flush eyes with water and contact physician. When handling batteries, wear
eye protection, chemical resistant gloves and protective clothing.
DISCLAIMER!
Due to inherent dangers associated with automotive maintenance
procedures, the manufacturer and all parties involved with the distribution
and/or sale of this equipment will not be held liable or responsible, either
wholly or in part, for any injury, damage or claims resulting in its
performance or the use of the instructions contained in this manual.

Battery Load Tester
The Battery Load Tester is a hand-held, diagnostic tool used to test 12V (volt) and
6V lead-acid type automotive batteries. A 10-second test determines the condition of the battery: Good, Weak or Bad. Further testing will identify possible problems in the charging and starting systems. Tests can be performed on fully or
partially charged batteries by inspecting the electrolyte or open-circuit voltage
and adjusting the values for temperatures other than 70°F (21.1°C).
If the electrolyte is accessible, measure its specific gravity with a hydrometer.
The specific gravity reading should be 1.225 or higher at 70°F (21.1°C). For
every 10°F (5.6°C) above/below 70°F (21.1°C), add/subtract 0.004 to/from the
reading.
The open-circuit voltage should be at least 12.45V at 70°F (21.1°C).
The Battery Load Tester contains a four-character LCD (liquid crystal display) to
display battery voltage, a switch to apply the test load and a red LED that is used
to indicate the condition of the alternator. The tester is powered by the battery
under test.
CAUTION!
Test procedures and information provided in this manual are intended
as general guidelines for engine tune-up and adjustments only. Con-
sult the applicable vehicle service manuals for all specific tests.
Before testing, read and follow all safety precautions.
Do not activate and hold the load switch for more than 15 seconds. This
will overload the tester resulting in damage and void the warranty.
Test Preparation
Multi-Battery Systems
In all multiple battery systems, all batteries must be tested separately. Batteries
may be connected in series, parallel or a combination of both. Only batteries
connected in series may remain connected during test. See Figure 1.
For series connections, all batteries are connected from the negative (-) terminal
of one battery, to the positive (+) terminal of the other. Only the negative terminal
of the first battery and the positive terminal of the last battery are to be connected
to the vehicle. Any number of batteries may be connected in a series. However,
each battery must be tested separately.
For all other connections (parallel or a combination of parallel and series), the
batteries must be disconnected and electrically isolated from each other.
