STEP FOUR
BASIC TEST
When battery voltage has recovered or 30 seconds has
passed, the ignition will be enabled and the display will
show:
The operator should quickly bring the engine to a speed
where the alternator can charge at a full rate (1500 to
2000 RPM), and before there has been enough charge
added for the battery to recover to the regulated volt-
age.
After a few seconds the display will beep and momen-
tarily show:

STEP FIVE
BASIC TEST
To compensate the measurement of battery CCA rating
(SAE Cold Cranking Amps), the operator can SELECT
one of three temperature ranges that best matches the
battery electrolyte.
SELECT degrees Celsius from: -10 to 0, 0 to 15, or over
15.
Press START to continue:
SELECT: Battery Temp.
DEG. C= over 15
TEST VARIATIONS
This choice will not be asked if recovery was over 30
seconds.
BASIC TEST
After the 15 second test the display will show:
When the operator stops cranking, a waiting period
begins which checks the voltage recovery time of the
battery. Good batteries will spring back in 1 or 2 sec-
onds. Worn out or undercharged batteries need over
10 seconds to recover. Make sure all battery drains
such as dome lamps are off during this test. Keep doors
closed.
