The SpeedCharge has a built-in
alternator tester that displays either an
accurate alternator voltage or an
estimate of the alternator’s relative
output compared to normal alternators.
The Alternator % values displayed
should be taken as general reference,
not precise diagnosis. The alternator
tester functions the same as the battery
tester (see previous section of this
manual for details) with a few differences.
TESTING SEQUENCE
There are three basic steps required to
use the SC-6000A as an alternator
tester.
1. Connect the SpeedCharge battery
clamps to the battery or charging
system. Be sure to follow all of the
precautions listed under “OPERAT-
ING INSTRUCTIONS”.
2. Connect the SpeedCharge power
cord to a 120 VAC outlet. Again, be
sure to follow all of the precautions
listed under “OPERATING INSTRUC-
TIONS”.
3. Start the vehicle and turn on the
vehicle’s headlights. Read the voltage
USING THE BUILT-IN ALTERNATOR TESTER
on the digital LED or press the
display mode button to set the tester
to “Alternator %” and read the
alternator percent.
TESTER STATUS LED’s
When the SC-6000A is operating as an
alternator tester, the status LED’s light
under the following conditions.
• The CHARGED (green) LED will light
if the output of the charging system is
at the normally desired level.
• The CHARGING (yellow) LED does
not light in the alternator test mode.
• The CHECK (red) LED lights if the
voltage is much higher or lower than
normally desired.
• When the tester display mode is set
to voltage, none of the status LED’s
light (it could be testing a battery or
an alternator).
ALTERNATOR TESTING NOTES
• The alternator percent display can
range from 0 to 199.
• The display mode cannot be set to
“Alternator %” during charging.
OVERVIEW
The SC-6000A has an engine start
function that can be used to jump start
your vehicle if the battery is low by
providing 60 amps of current to assist
engine cranking.
STARTING SEQUENCE
There are a few basic steps involved
when using the engine start function.
1. Connect the SpeedCharge battery
clamps to the battery or charging
system. Be sure to follow all of the
precautions listed under “OPERAT-
ING INSTRUCTIONS”.
2. Connect the SpeedCharge power
cord to a 120 VAC outlet. Again, be
sure to follow all of the precautions
USING YOUR ENGINE STARTER
listed under “OPERATING INSTRUC-
TIONS”.
3. Press the CHARGE RATE button
until the 60 START indicator is lit.
4. Crank the engine until it starts or 8
seconds passes.
5. If the engine did not start, wait for the
SpeedCharge to cool then repeat
step 4.
During the starting sequence listed
above, the charger is set to one of three
states.
1. Wait for cranking - The charger
waits until the engine is actually
being cranked before delivering 60
amps for engine start. The charger
delivers charge at a rate of 10 amps
