Using Your Alternator Tester
1. Start the engine and turn on the vehicle’s headlights.
2. Read the voltage on the digital display or press the DIGITAL DISPLAy button
to set the tester to ALTERNATOR %. The alternator percent will display a range
from 0 to 199. See page 11 of the Owner’s Manual for details.
Using Your Engine Starter
1. Press the BATTERy SIZE button until the ENGINE START LED glows.
2. Crank the engine for no more than 5 seconds until it starts. The digital display
will count down from 5 to 0 seconds.
3. If engine does not start within 5 seconds, stop cranking the engine. The
SC-7500A needs to cool 3 minutes between crankings. It will automatically
count down from 180 to 0 seconds, or 3 minutes. No power is delivered to the
battery during this time.
4. During the 3-minute cool down period, the ENGINE START LED will blink.
After the cool down period ends and the charger is ready for another attempt
to crank the engine, the ENGINE START LED light will stay on continuously.
5. If necessary, repeat steps 2 through 4 until engine starts. After engine starts,
unplug 120V AC electrical power cord before disconnecting the output clamps
from the battery. See page 6 of the Owner’s Manual for details.
Charging Your Battery
1. Press the BATTERy TyPE button to select your battery type: 12V STANDARD;

being charged: SMALL BATTERy or MEDIUM TO LARGE BATTERy. The
CHARGING LED glows when charging begins and shuts off automatically
after the battery is charged.

If the BATTERy SIZE button is pressed enough times, it is possible for
no charge rate to be selected. If all the BATTERy SIZE LEDs are off, then no
rate is selected and the SC-7500A is in Test Mode. To return to Charge Mode,
press the BATTERy SIZE button until one of the charge rate LEDs glows. See
page 4 of the Owner’s Manual for details.
3. The green CHARGED LED will turn on after the battery is charged and the
charger will automatically change to Maintain Mode. See page 7 of the Owner’s
Manual for details.
4. To immediately use your vehicle, unplug the battery charger from the 120V
AC electrical outlet, remove the battery charger’s clamps from the vehicle and
have a great day!
