D1. Perform charging system output test; determine needed action. P-1

I accomplished this task in several ways. I first read the charging system diagnosis chapter, then I completed the related Argo modules that where related to charging systems and their testing. I then tested the alternator output on the Chevrolet Corsica. I did this by hooking up the gr8 1200 and performing a charging system output test.

D2. Diagnose (troubleshoot) charging system for causes of undercharge, no-charge, or overcharge conditions. 

I accomplished this task by reading the charging system diagnosis chapter in our electrical book. I furthered my knowledge on this topic by completing the charging system diagnosis Argo modules on Argo. I proved my knowledge of this topic by performing a charging voltage test to determine if the alternator is charging the battery properly, overcharging the battery or undercharging it. I did this test on the Jeep Grand Cherokee in the shop here at Northern. 

D3. Inspect, adjust, and/or replace generator (alternator) drive belts; check pulleys and tensioners for wear; check pulley and belt alignment. 

I accomplished this task by reading about drive belts in the charging system chapter in the Electrical book. I furthered my knowledge by doing research abut different types of drive belts. I learned about V belts, Serpentine belts, and their applications.  I also learned about drive belts and pulleys and tensioners by completing the drive belt module and quiz on Argo. I put my knowledge to work by removing, inspecting, and reinstalling the drive belt on the Old Chevy truck in the shop. 

D4. Remove, inspect, and/or replace generator (alternator). P

I accomplished this task by learning the proper procedure of how to remove a generator out of a car by reading the charging system diagnosis chapter in the Electrical book. I also learned how to do this by observing other people remove an alternator in my home town. I did this task myself on the Jeep Grand Cherokee in the shop. I made sure to remove the native battery terminal on the battery before I began any repairs.  

D5. Perform charging circuit voltage drop tests; determine needed action.

I accomplished this task by learning how to perform the different voltage drops by reading the charging system diagnosis chapter in the Electrical book. I learned how to perform these tests furthermore thru completing the Argo modules that had to do with the voltage drop testing.  I also performed the charging circuits voltage drop tests on the charging circuits of the Jeep Grand Cherokee, and the Chevy Corsica.
