Diagnosis

Battery

Common causes of failure

A battery is not designed to last indefinitely; however, with proper
care, it will provide many years of service. If the battery performs
satisfactorily during test but fails to operate properly for no appar-
ent reason, the following are some factors that may point to the
cause of trouble :
• Accessories left on overnight or for an extended period with-
out the generator operating.
• Slow average driving speeds for short periods.
• Electrical load exceeding generator output particularly with
addition of aftermarket equipment.
• Defects in charging system such as high resistance, slipping
drive belt, loose generator output terminal, faulty generator
or voltage regulator. Refer to "Generator" in this "Diagnosis"
section.
• Battery abuse, including failure to keep battery cable termi-
nals clean and tight or loose battery hold down.
• Mechanical problems in electrical system such as shorted or
pinched wires.

Visual inspection

Check for obvious damage, such as cracked or broken case or
cover, that could permit loss of electrolyte. If obvious damage is
noted, replace battery. Determine cause of damage and correct
as needed.
