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 apparent
reason, the following are some factors that may point to the cause
of trouble:
Accessories left on overnight or for an extended period without
the generator operating.
Slow average driving speeds for short periods.
Electrical load exceeding generator output particularly with addi-
tion 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 terminals
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 cov-
er, that could permit loss of electrolyte. If obvious damage is noted,
replace battery. Determine cause of damage and correct as need-
ed.
