Battery test results
Action to be taken
Message
GOOD & PASS
Battery okay, battery does not need
charging.
GOOD & RECHARGE Charge battery.
RECHARGE RETEST Fully charge the battery and retest.
Failure to fully charge a new battery
before testing may cause false readings. If
RECHARGE RETEST appears again after
you fully charge the battery, replace the
battery.
MARGINAL BATTERY Replace battery immediately or soon.
BAD & REPLACE
Replace battery and retest. A
BAD & REPLACE result may also mean
a poor connection between the clamps
and the battery. After disconnecting the
clamps, retest the battery using the out-
of-vehicle test before replacing it.

System test
The following characteristics are evaluated during
the system test for 12 V and 24 V starter/generator
systems:
R
Voltage dips during the starting process
R
Harmonic content of the charging voltage without
load
R
Charging voltage under load
!
Before starting the system test, inspect the
alternator drive belt. A belt that is glazed or worn,
or lacks the proper tension, will prevent the
alternator from achieving the rpm levels needed for
the test.
i
The performance of the starting and charging
systems depends on the battery's condition. It is
important that the battery is good and charged
before a system test is performed.
i
Before the engine is started, switch off all vehicle
consumers (e.g. lights, air conditioning, radio).
i
To measure the charging voltage under load, switch
on consumers such as high beam and rear window
heater. Do not switch on cyclic loads such as air
conditioning or windscreen wipers.
i
If you test older diesel engines, accelerate the
engine to 2500 rpm for 15 seconds.
