9. Press ENTER to determine the amount of ripple from the charging system to the battery. One of two testing
results will be displayed, along with the reading taken.
}
Ripple Detected
Diodes function well in the alternator / stator.
}
No Ripple Detected
One or more diodes in the alternator are not functioning or there is stator damage. Ensure that the alternator
mounting is sturdy and that the belts are in good shape and functioning properly. If the mounting and belts
are good, replace the alternator.
10. Press ENTER to continue testing the charging system with accessory loads. One of two results will be
displayed.

11. Press ENTER when the charging system test is completed. Turn all accessory loads and engine off. Press ENTER
to return to Step 1 or remove the test clamps from the battery posts after completion of testing to end test.
8 Glossary
Gelled Electrolyte (GEL) Battery
A lead-acid electric storage battery that:
}
Is sealed using special pressure valves and should never be opened.
}
Is completely maintenance-free. (However, connections must be retorqued and the battery cleaned periodically.)
}
Uses thixotropic gelled electrolyte.
}
Uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded
lead-acid battery (particularly in deep-cycle applications).
}
Is non-spillable, and therefore can be operated in virtually any position. (However, upside-down installation is
not recommended.)
Absorbent Glass Mat (AGM) Battery
A lead-acid electric storage battery that:
}
Is sealed using special pressure valves and should never be opened.
}
Is completely maintenance-free. (However, connections must be retorqued and the battery cleaned periodically.)
}
Has all of its electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers.
}
Uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded
lead-acid battery (particularly in deep-cycle applications).
}
Is non-spillable, and therefore can be operated in virtually any position. (However, upside-down installation is
notrecommended.)
Valve Regulated Lead Acid (VRLA) Battery
A battery that is sealed Maintenance Free with a “Bunce” Valve or Valves in the top that opens when a preset pres-
sure is realized inside the battery and lets the excess gas pressure out. Then the valve resets itself.
