BATTERY CONDITION ANALYSIS
LOAD TEST / 15 Sec. (Display Reading)
Battery Condition
OK (Green area)
Battery Capacity is good. May or may not be fully charged.
Check the charge state by testing the Specific Gravity (SG)
with a Hydrometer. If SG is less than full charge, check for
possible charging system trouble. Recharge to full level.
BAD (Red area)
If the DC Volt Meter needle is failing, the battery is
defective or has a bad cell. For a quick check, turn the
Load Knob down (counterclockwise) and note DC Volts
Meter reaction. If voltage recovers to its full potential after
only a few seconds, the battery is probably defective. If the
voltage recovers slowly, the battery may only be run down.
Check specific gravity level, recharge, and retest.
CHARGING SYSTEM (Alt. & Reg. Test)
If the DC Volt Meter needle reads OK, charging system
is functional. If it falls on the low red or high red areas,
charging system may be malfunctioning.
STARTER MOTOR TEST
If starting your vehicle is difficult, you may have unnecessary
starter motor draw, which dramatically shortens battery life.
This test identifies starter motor performance.
1. Make sure your engine is running at normal operating
temperature, and that the battery is fully charged and in
good condition.
2. Connect the Red Clamp to the positive (+) terminal
post on the battery. Connect the Black Clamp to the
negative (-) terminal post on the battery.
3. Turn the Load Knob (C) counterclockwise to the OFF
position.
4. Disable the engine to make sure the car will not start.
Refer to your vehicle’s service manual.
5. While watching the DC Volt scale, crank the engine
briefly to determine the voltage reading during
cranking. A display reading of 9 volts or less indicates
excessive current draw. This may be caused by a bad
connection of a failing starter motor, or the battery
is too small for the vehicle’s requirements. Consult a
qualified mechanic.
6. When starter motor test is complete, remove Black (-)
Clamp from battery first; then remove Red (+) Clamp.
INSPECTION, MAINTENANCE, AND CLEANING
1. Periodically check all nuts, bolts, and screws for
tightness.
2. Store in a clean, dry location.
3. Clean the outside of the unit with a damp cloth.
Never use solvents to clean any parts of this tool. Use
compressed air to blow out debris from the load vents.
Allow tool to dry completely before use.
4. After each use, clean the cable clamps of any possible
battery electrolyte. Apply a thin coat of silicon grease to
prevent corrosion.
