CHARGING SYSTEM VOLTAGE LOW WHEN TESTING WITH ACCESSORY LOADS
The alternator is not providing sufficient current for the
system’s electrical loads and the charging current for the
battery. Check the belts to ensure the alternator is rotat-
ing with the engine running. If the belts are slipping or broken, replace the belts and re-
test. Check the connections from the alternator to the battery. If the connection is loose
or heavily corroded, clean or replace the cable and retest. If the belts and connections
are in good working condition, replace the alternator.
CHARGING SYSTEM VOLTAGE NORMAL WHEN TESTED WITH ACCESSORY LOADS
The system is showing normal output from the alternator.
No problem detected.
11. Press «ENTER» when 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.
GLOSSARY
What is a GEL battery?
A gel battery is a lead-acid electric storage battery that:
• is sealed using special pressure valves and should never be opened.
• is completely maintenance-free.
• 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.
What is an AGM battery?
An AGM battery is a lead-acid electric storage battery that:
• is sealed using special pressure valves and should never be opened.
• is completely maintenance-free.
• 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 not recommended.
