INSTRUCTIONS FOR USE
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 danger
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 recharging.
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 following 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-POWERCHECK 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 procedure: 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 battery 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
