REPAIR PROCEDURE ALTERNATOR TEST



1. Ask the client to describe the events that led up to the problem. Many charging system complaints are caused by leaving the headlights or interior



lights



on, headlight flicker (a normal condition), or installing aftermarket accessories with a high parasitic draw that drains the battery.



2. Visually inspect the alternator and battery cables and grounding straps to confirm that the connections are clean and tight. If there are any



damaged parts or loose connections, repair them as needed.



3. Place the GR8 AST by the driver's side front tire.



NOTE:



Make sure the engine is at normal operating temperature before testing. If not, hold the engine speed at 3,000 rpm in Park (P) or Neutral (N)



until the radiator fan comes on twice, then let it idle.



4. With the engine OFF, turn the GR8 ON, and connect it to the vehicle:



^ Connect the negative (-) lead to the negative battery terminal.



^ Connect the positive (+) lead to the positive battery terminal.



5. In the main menu, scroll over to the SYSTEM icon, and press the SELECT key.

12. Enter the battery's CCA, and press NEXT to begin the battery testing.



13. Wait until the initial battery testing is complete.



14. Zero the amp clamp following the on-screen instructions, making sure the clamp jaws are completely closed during the procedure.



*15. Place the clamp around the positive (+) alternator cable. This will be simple on most models, but on some it may be difficult because of



obstructions or tight spaces.



NOTE:



^ Testing is done at the B+ cable to help rule out other factors in the vehicle's charging system and to increase testing accuracy.



^ Make sure the amp clamp is clear of any moving engine parts.*

NOTE:



If you do not rev the vehicle within the first 10 seconds, or the tool cannot detect the engine speed, you will have to rev the engine to 3,000-3,500



rpm, hold at that rpm level, and hit NEXT to continue.
