REVIEWING TEST RESULTS
The ATD5493 remote stores the last test results in memory for review while
connected
to the test battery
or
at a later time
when
disconnected
from the battery. The review prompt will only display if data is stored in the memory and has not been
erased.
To review stored data, press and hold the
MENU/ON-OFF
button until the display reads “
WAITING TO CONNECT
,” then
release the button
.
Wait approximately 15 seconds for the display to show
REVIEW
. Press enter to review test data stored in
the tester.
Press
NEXT +
to review Starter Test data (if stored) and

Using the USB Adapter
Introduction
The USB adapter allows the user to download the stored test data in the ATD 5493 into your computer. Once
the CD program is installed, the test data is stored in a Windows based program for immediate printing or saved
in a file for future reference.
CHARGING SYSTEM TEST:
IMPORTANT: Engine must be off before testing charging system.
Charging system can also be road tested while driving vehicle*.
After completing the starter test, press
NEXT +.
The display will prompt the user
TEST CHARGING SYSTEM
.
(Note:
the maximum starter/charging voltage is 36V).
To test the charging system:
1.
Press
ENTER
←
:
The user will be prompted to
START THE ENGINE (ACCESSORIES OFF)
. The tester will
automatically detect that the engine has started and will display
ENGINE STARTED PLEASE WAIT
.
2.
The display will prompt the user to Press
NEXT +
and
REV ENGINE FOR 15 SECONDS
. After revving, the
user will be prompted to
TURN ON ACCESSORY LOADS
(lights & AC or heater) and press
NEXT +
again.
3.
The user will be prompted to
REV ENGINE FOR 15 SECONDS
again. After revving the display will show one of
the following the test results: (Note some versions will prompt the user to turn off accessory loads after revving
and then press
NEXT +.)
CHARGING SYSTEM IS OK
NO CHARGING:
The alternator is not supplying a charging voltage to the battery. Check also for loose,
slipping or broken alternator belt
BAD DIODE REPLACE ALTERNATOR:
The tester detected
excess ripple
coming from the alternator
indicating defective diode(s). If diodes are not replaceable, replace alternator.
BAD DIODE AND/OR CHECK CONNECTIONS:
The tester detected low charging voltage that could be
caused by a bad diode (although alternator ripple is within normal limits) or high resistance connections. If
connections and diode are found to be good, check regulator and replace if necessary.
REPLACE REGULATOR
: The tester detected abnormally
high alternator output voltage caused by a defective regulator.

ROAD TESTING THE CHARGING SYSTEM
Connect the local unit to the battery making sure it is properly secured. Turn on the Remote and wait for
the connection to sync. Set the vehicle charging voltage and press Enter. The display will show the
battery SOC (state of charge). Start engine and begin road testing at various speeds with and without
accessory loads. The display will show the real time alternator output. Check manufacturer’s
specifications for proper charging voltage during road test.
Warning! Risk of accident.
Two people should be in the vehicle when driving on the road, one to drive and the other to attend to the
equipment. Accidents can occur when attention is not solely given to driving.
Road test: Extra precautions are required to keep the local unit away from hot or moving parts while a
vehicle is driven on the road. It may be necessary to secure the local unit to frame or body parts with wire or
nylon ties to insure that the local unit does not change position while the vehicle is being driven.
