Caution!

The engine should be at operating temperature.

Proceed as follows:

- Attach the pole pliers (+) to the positive terminal (+) of the bat-

tery and the black, isolated clamp to the negative terminal (-) of

the battery. Gently shake the pole pliers at the terminal to ensu-

re contact.

- switch off all power loads (lights, fans, discs, boosters, etc.),

start the engine and hold at a slowing increasing idle speed of

approx. 1500 RPM.

- never press the button "LOAD" (5) during this measurement

- read the voltage value on the digital display

- now turn on the high-beam headlights and set your fans to the

highest level. The voltage display should change no more than

around approx. 0.1 to 0.3 volts (V).

If the display remains relatively stable, the charging system of your

motor vehicle is OK. If the voltage changes to more than approx. 0.3

V (above or below), you have your charging electrical equipment

(headlights, regulators, brushes, drive-belts, cables, points, cables,

plug connector etc.) examined by a mechanic.

D Starter test

With this test, it can be determined relatively easily whether your

vehicle starter does not take enough current from the battery. Cur-

rents of more than approx. 200 Amp can be produced. Make abso-

lutely sure that the battery is correct before this test. If the battery is

weak or defective, then this test is not useful. Proceed as follows:
