AR15.40-P-5011P Check Charging Current of Alternator

Test Charge Current Of Generator

Shown On Model 203:

DANGER:
- Risk of explosion from explosive gas. Risk of poisoning and caustic burns from swallowing battery electrolyte. Risk of injury through burns to skin and eyes from battery acid or when handling damaged lead-acid batteries
- No fire, sparks, naked flames or smoking.
- Wear acid-resistant gloves, clothing and goggles. Pour battery electrolyte only into suitable and appropriately marked containers.

1 Prerequisites for testing generator
2 Check regulation voltage of generator (G2)
3 Connect multimeter (003)

See "Commercially Available Tools - Multimeter" given below.

4 Connect volt / ampere tester with load resistor (079)

See "Commercially Available Tools - Volt-ampere Tester with Load Resistor" given below.

5 Read off charging current at model plate of generator (G2)

DANGER:
- Risk of accident. Accidents may result if the vehicle starts off unintentionally with the engine running. Risk of injury as working around the engine during start-up or while running may result in contusions and burns Start engine
- Secure vehicle to prevent it from moving.
- Wear closed and snug-fitting work clothes. Do not grasp hot or rotating parts.

7 Check charging current

See "Test Values Of Regulator" given below.

8 Charge battery (G1)

NOTE:
- With Volt ampere tester with load resistance (079), until max..charging current of alternator (G2) is reached.
- The regulation voltage must therefore not drop under 12,7 v. Charging current below specified value

Check diodes of alternator (G2). See "Commercially Available Tools - Volt-ampere Tester With Load Resistor" given below.

9 Switch off engine
10 Disconnect volt / ampere tester with load resistor (079)
11 Disconnect multimeter (003)
