BATTERY TESTER
OPERATOR AND SAFETY MANUAL
The BEST 6044 is designed to test electrical systems on 12, 12/24, and 24 volt vehicles. It can test and evaluate
starters, batteries, alternators, regulators, wiring connections, and other electrical equipment in the low voltage circuits
in the vehicle. Before operating this unit, thoroughly familiarize yourself with the safety instructions included in this
booklet and in the service manual.

FEATURES OF THE BEST 6044 INCLUDE:
Large, easy to read, LED digital AMPS and VOLTS
meters. The VOLTS meter reads voltages to ±40
volts DC when reading the differential voltage and
up to 40.0 volts DC for the battery voltage. The
AMPS meter reads DC currents up to 999 amps.
The input impedance of the differential voltage is 2
megohms for accurate testing of solid state
circuits.
The load is rated 500 amps on 12 volt batteries for
load testing batteries up to 1000 CCA capacity.
Fixed loads designed to insure longer life.
Amp probe zero button allows for maximum
accuracy in AMPS reading.
LOAD ON light indicates the load is actuated and
serves as a reminder to not disconnect leads while
load is on.
AMPS meter reads both + and - amps for easy
diagnosis of leakage current problems.
Unit monitors the voltage ripple letting you know
when alternator output diodes have failed.
The electronic circuits are protected against
reverse voltages caused by connecting leads
incorrectly.
The electronic circuit board has a protective
coating to prevent damage and meter inaccuracy
due to moisture and dirt.
Heavy duty leads are single extended so that they
may be used for testing at points up to 15 feet
apart.
The clamps on the heavy duty lead are vinyl
dipped and have a flexi-spring stain relief to
prevent cable damage. Solid copper jaws provide
better electrical conduction and are field
replaceable.
Heavy duty leads have internal tracer lead wires
for voltage reading the battery voltage. These
leads should not be attached to any voltage source
that could rise above 45 VDC.
The light gauge voltage sensing leads (red and
black) have small test clips to allow testing at
points where the heavy duty leads can not reach.
Use the leads when the unit is set for the external
voltage (differential voltage) reading. The leads
can test points in a vehicle up to 15 feet apart and
read voltages up to 40 VDC.
The inductive AMP PICKUP has 10 foot long lead
to allow for testing in hard to reach areas.
All leads are long enough to test trucks, "high-rise"
four wheel drive, or off road vehicles.
The optional cart has a long wheel-base for
greater stability when moved over rough surfaces
or cracked floors.
Optional printer: prints a report of all the results of
any test performed by the 6044.
