MANUAL: KFZ-POWERCHECK
1. TEST FOR VEHICLE ALTERNATOR
A faulty alternator will result in damage to a battery either
through undercharging or overcharging. Connect red clip
to battery + and black clip to battery -.
a) Run engine with all electrical equipment (headlamps,
windscreen wipers, rear screen demist etc.) switched
OFF.
b) Run engine with all electrical equipment switched ON.
For both tests, green LED "Alternator O.K." (Lichtmaschine
O.K.) should be on, red LED "Alternator defective /
Overcharging" (Lichtmaschine defekt / Überladung)
should be off, for all engine speeds above idle. RED ON is
an indication of alternator overcharging, which will result
in the frequent need for the replacement of lamp bulbs,
the need for frequent battery topping up with distilled
water, and the premature failure of batteries, particularly
sealed batteries. RED and GREEN both OFF is an indication
that the alternator is undercharging or is not charging at
all. If the alternator is not charging at all, then the battery
will quickly become discharged, and eventually the lights
will become dim and the engine will refuse to start. If the
alternator is merely undercharging, then there is a dan-
ger that the battery will become flat, particularly if the car
has short stop / start journeys, or on journeys when the
headlamps, windscreen wipers, rear screen demist etc.
are used. The battery may need frequent manual rechar-
ging. A battery maintained in a partially discharged state
will have a shortened life.
2. TEST OF BATTERY CHARGE
The state of charge of a battery can be measured by an
accurate measurement of battery voltage. However, it
takes some time for a battery voltage to settle down fol-
lowing a period of charge or discharge.
If the battery is not in the car and has not been used
for some time (over 12 h), simply connect KFZ-POWER-
CHECK to the battery as shown in figure 1, and observe
the lamp indicators. If the battery is in the car and has
recently been used, then carry out the following proce-
dure: switch on the car headlamps for 1 minute without
the engine running (this removes the 'surface charge'
from the recent charging). Then switch off the headlamps
and disconnect the battery from the car. Wait at least 15
minutes before connecting KFZ-POWERCHECK to the bat-
tery and observing the lamp indicators (Batterie Ladungs
Zustands Anzeige).
3. BATTERY POWER TEST
This test will indicate whether the battery is faulty and
should be replaced. Ensure that the battery has recently
been fully recharged. Connect the KFZ-POWERCHECK as
shown in figure 1. Switch the ignition of your car on and
run as much electrical equipment as possible (head-
lamps, windscreen wipers, rear screen demist, etc.) for
approx. 3 minutes. If the battery is faulty, the green LED
"Battery power test" (Batterie Belastungstest) will turn
off during the test. When the green LED shows OK., the
battery should have a useful life left.
