20 Reduce the engine speed to idle.
On completion of the generator output test, 21 Stop the engine. 22 Disconnect the battery ground cable P-5 at the battery. 23 Remove the multimeters. 24 Reconnect the generator positive lead P-9. 25 Reconnect the battery ground cable P-5 to the battery. Engine RPM............................................................ 1900 Load................................................................5.0 – 10 A Output Voltage...........................................13.8 – 15.4 V Charging Circuit Voltage Drop Test Prerequisites Before testing the generator output, ensure that: • all generator circuit connections are clean and tight, • the generator is always connected to the battery during testing (to prevent damage to the diodes), • the battery is fully charged, and • the specific gravity does not vary more than 0.025 between cells. (It is recommended the average specific gravity Carry out a load test on the battery to determine its ability to supply and accept current. This is a good indicator of the Inspect the drive belt and tensioner markings to determine if the drive belt is within operating limits. Replace the belt if it For further details, refer to 6A1 Engine Mechanical – V6. Voltage Drop Test
Ensure the generator connections are clean 1 Connect the positive lead of a multimeter set to measure voltage to the generator terminal P-9. 2 Connect the negative lead of the multimeter to the battery positive post. 3 Switch the headlamps on. 4 Start the engine. 5 Increase the engine speed to approximately 2500 r.p.m. 6 Record the voltage reading. 7 Reduce the engine speed to idle. |
