charger is not capable of producing specified current
value, set its charging current as close to that value as
possible.
lKeep battery away from open flame while it is being
charged.
lWhen connecting charger, connect leads first, then turn
on charger. Do not turn on charger first, as this may
cause a spark.
lIf battery temperature rises above 60ÉC (140ÉF), stop

lAfter starting charging, adjustment of charging current is not necessary.
CAUTION:
lDo not use quick charge method on a battery whose specific gravity is less than 1.100.
lSet initial charging current to value specified in Fig. 6. If charger is not capable of producing
specified current value, set its charging current as close to that value as possible.
lKeep battery away from open flame while it is being charged.
lWhen connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.
lBe careful of a rise in battery temperature because a large current flow is required during quick-
charge operation.
If battery temperature rises above 60ÉC (140ÉF), stop charging. Always charge battery when its
temperature is below 60ÉC (140ÉF).
lDo not exceed the charging time specified in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.

MAGNETIC SWITCH CHECK
lBefore starting to check, disconnect battery ground cable.
lDisconnect ``M'' terminal of starter motor.
1. Continuity test (between ``S'' terminal and switch body).
lNo continuity ... Replace.
2. Continuity test (between ``S'' terminal and ``M'' terminal).
lNo continuity ... Replace.
PINION/CLUTCH CHECK
1. Inspect pinion teeth.
lReplace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).
lReplace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
lIf it locks or rotates in both directions, or unusual resistance
is evident. ... Replace.
BRUSH CHECK
Brush
Check wear of brush.
Wear limit length:
Refer to SDS, EL-33.
lExcessive wear ... Replace.

Brush spring pressure
Check brush spring pressure with brush spring detached from
brush.
Spring pressure (with new brush):
Refer to SDS, EL-33.
lNot within the specified values ... Replace.
Brush holder
1. Perform insulation test between brush holder (positive side)
and its base (negative side).
lContinuity exists. ... Replace.
2. Check brush to see if it moves smoothly.
lIf brush holder is bent, replace it; if sliding surface is dirty,
clean.
YOKE CHECK
Magnet is secured to yoke by bonding agent. Check magnet to
see that it is secured to yoke and for any cracks. Replace mal-
functioning parts as an assembly.
CAUTION:
Do not clamp yoke in a vice or strike it with a hammer.
ARMATURE CHECK

lNo continuity ... Replace.
2. Insulation test (between each commutator bar and shaft).
lContinuity exists. ... Replace.
3. Check commutator surface.
