STARTING AND CHARGING SYSTEM 6D3-9



Generator Power
1. Adjust load resistor, if the required load currents are not attained.
2. The shape of the voltage curves on oscilloscope curve should be regular.
3. Test value: 5 to 7A.
4. If the required minimum current intensity is not attained, o
r
if the oscilloscope picture shows variations, the alternator
should be overhauled.

6D3-10 STARTING AND CHARGING SYSTEM
The generator has four external connections; the "B+" lead to
battery positive, "L" lead to the warning lamp circuit(max. 2
watts), "S" lead to battery positive terminal for battery sensing
and an earth connection.

Explanation of type inscripiton
Example:KC-A--> 14V 50-90A.

K = Code for Stator OD(126mm OD).
C = Compact Generator.
A = Ausland (countries other than Germany)
> = Direction of rotation(clockwise).
14V = Generator Operating Voltage.
50A = Stabilised output at 25 C at 1800 RPM./13.5
Volts.
90A = Stabilised output at 25 C at 1800 RPM./13.5
Volts.

Generator Connetions.
B+ : Battery Main Connection (battery positive)
S : Battery Sense Connection(battery positive)
L : W aring lamp(via warning lamp to Ignition switch)
