4) Install spring (5) and magnetic switch (2) to plunger 

and then tighten magnetic switch inner screw (4).

CAUTION

!

 

With marks (1) on magnetic switch (2) and 
planetary carrier shaft assembly (3) marked 
before remove aligned to each other.

 

5) Install front housing (2) and then tighten magnetic 

switch screw (1).

6) Install through bolts (2) and then tighten through 

bolts.

7) Connect lead wire to terminal “M” (1).

Starting Motor Inspection

S6JB0A1926004

Plunger
Inspect plunger for wear. Replace if necessary.

Magnetic Switch
Push in plunger and release it. The plunger should 
return quickly to its original position. Replace if 
necessary.

Pull-in coil open circuit test

Check for continuity across magnetic switch “S” terminal 
and “M” terminal. If no continuity exists, coil is open and 
should be replaced.

Hold-in coil open circuit test
Check for continuity across magnetic switch “S” terminal 
and coil case. If no continuity exists, coil is open and 
should be replaced.

Pinion and Over-Running Clutch
• Inspect pinion for wear, damage or other abnormal 

conditions. Check that clutch locks up when turned in 
direction of drive and rotates smoothly in reverse 
direction. Replace if necessary.

• Inspect spline teeth for wear or damage. Replace if 

necessary. Inspect pinion for smooth movement.

General Description

Battery Description

S6JB0A1A11001

The battery has three major functions in the electrical system.
• It is a source of electrical energy for cranking the engine.
• It acts as a voltage stabilizer for the electrical system.
• It can, for a limited time, provide energy when the electrical load exceeds the output of the generator.

Carrier and Hold-Down
The battery carrier should be in good condition so that it will support the battery securely and keep it level.
Before installing the battery, the battery carrier and hold-down clamp should be clean and free from corrosion and 
make certain there are no parts in carrier.
To prevent the battery from shaking in its carrier, the hold-down bolts should be tight enough but not over-tightened.

Electrolyte Freezing
The freezing point of electrolyte depends on its specific gravity. Since freezing may ruin a battery, it should be 
protected against freezing by keeping it in a fully charged condition. If a battery is frozen accidentally, it should not be 
charged until it is warmed.

Sulfation
If the battery is allowed to stand for a long period in discharged condition, the lead sulfate becomes converted into a 
hard, crystalline substance, which will not easily turn back to the active material again during the subsequent 
recharging. “Sulfation” means the result as well as the process of that reaction.
Such a battery can be revived by very slow charging and may be restored to usable condition but its capacity is lower 
than before.

Built-in Indicator (if equipped)
The battery has a built-in temperature compensated indicator (1) in the top of the battery. This indicator is to be used 
with the following diagnostic procedure. 
When checking the indicator, make sure that the battery has a clean top. A light may be needed in some poorly-lit 
areas.
Three types of indication available under normal operation are as follows.
