Check The Generator's Charging Current - Ar15.40-S-5011E

Type 907 with Motor 274, 642, 651 

G13789907
WARNING Risk of accident  by starting up automatically while the engine is running. Risk of injury  from bruises and burns when intervening during the starting process or while the engine is running Secure the vehicle against starting by itself AS00.00-Z-0005-01A
INSPECT Check     
1 Check and ensure the preconditions for the generator test.   AR15.40-S-5009E 
2 Check and ensure the preconditions for the generator test.   AR15.40-S-5010E 
3 Attach the multimeter (003) with DC current clamp (065) to the electrical line of the generator (G2) according to the connection diagram.    
4 Attach the load tester (079) to the on-board power supply battery (G1) according to the connection diagram.    
REFER TO SPECIAL TOOLS 000 588 03 19 00 Stress tester   WS15.00-P-0027B 
5 Start the motor.    
6 Check the charging current of the generator (G2). IMPORTANT Check the charging current with increased engine speed, whereby the on-board power supply battery (G1) is loaded with the load tester (079). Change the load resistance until the maximum charging current, depending on the version of the generator (G2), is reached. The charging voltage must not drop below 12.7 V. If the maximum charging current is not reached,

Check generator diodes (G2).
