If you have completed an out-of-vehicle test, the display alternates be-
tween the battery test results and the message PRESS  FOR TO PRINT.
Because the printer is powered by the voltage of the battery you are test-
ing the battery voltage must be greater than 9 volts. Keep the clamps
connected and press ENTER. For more information about the printer, see
"Changing the Printer Paper" on page 16 and "Troubleshooting Printer
Problems" on page 16.
To quit before printing, disconnect the clamps. Remember to print out your
test results before the next test.
IMPORTANT: The tester retains the results of the last test only. When you
start a new test, the last results are overwritten.

Starter System Test

If you have completed an in-vehicle test, the display alternates between
the battery test results and the message PRESS  FOR STARTER TEST.
To continue, start the engine at the prompt.
The display alternates between the decision on the starter system and the
measured voltage drop.
Return the battery to service.
Fully charge the battery and return it to
service.
Fully charge the battery and retest. Failure
to fully charge the battery before retesting
may cause inaccurate results. If CHARGE &
RETEST appears again after you fully charge the
battery, replace the battery.
Replace the battery and retest. A REPLACE
BATTERY result may also mean a poor connection
between the battery cables and the battery. After
disconnecting the battery cables, retest the battery
using the out-of-vehicle test before replacing it.
Replace the battery.
