CAUTION:
+Do not use standard charge method on a battery whose speci®c gravity is less than 1.100.
+Set charging current to value speci®ed in Fig. 4. If charger is not capable of producing speci®ed
current value, set its charging current as close to that value as possible.
+Keep battery away from open ¯ame while it is being charged.
+When connecting charger, connect leads ®rst, then turn on charger. Do not turn on charger ®rst,
as this may cause a spark.
+If battery temperature rises above 60ÉC (140ÉF), stop charging. Always charge battery when its
temperature is below 60ÉC (140ÉF).

CAUTION:
+Do not use quick charge method on a battery whose speci®c gravity is less than 1.100.

speci®ed current value, set its charging current as close to that value as possible.
+Keep battery away from open ¯ame while it is being charged.
+When connecting charger, connect leads ®rst, then turn on charger. Do not turn on charger ®rst,
as this may cause a spark.
+Be careful of a rise in battery temperature because a large current ¯ow 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).
+Do not exceed the charging time speci®ed in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.

MAGNETIC SWITCH CHECK
+Before starting to check, disconnect battery ground cable.
+Disconnect ``M'' terminal of starter motor.
1. Continuity test (between ``S'' terminal and switch body).
+No continuity ... Replace.

2. Continuity test (between ``S'' terminal and ``M'' terminal).
+No continuity ... Replace.
PINION/CLUTCH CHECK
1. Inspect pinion teeth.
+Replace pinion if teeth are worn or damaged. (Also check con-
dition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).
+Replace 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.
+If 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-51).
+Excessive wear ... Replace.
Brush spring pressure
Check brush spring pressure with brush spring detached from
brush.

Refer to SDS (EL-51).
+Not within the speci®ed values ... Replace.
Brush holder

Assembly
Apply high-temperature grease to lubricate the bearing, gears and
frictional surface when assembling the starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance ``!''
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance ``!'' between the front edge
of the pinion and the pinion stopper.
Clearance ``!'':
Refer to SDS (EL-51).
Movement ``!''
Compare movement ``!'' in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
Movement ``!'':

Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.
