Performance Test
PULL-IN TEST
Connect battery to magnetic switch as shown.
Check that plunger and pinion move outward.
If plunger and pinion don’t move, replace magnetic switch.
HOLD-IN TEST
While connected as above with plunger out, disconnect negative
lead from terminal “M”.
Check that plunger and pinion remain out.
If plunger and pinion return inward, replace magnetic switch.
PLUNGER AND PINION RETURN TEST
Disconnect negative lead from starting motor body.
Check that plunger and pinion return inward.
If plunger and pinion don’t return, replace magnetic switch. Starting motor does
not stop runningFused contact points of magnetic switch Replace magnetic switch.
Short-circuit between turns of magnetic switch coil
(layer short-circuit)Replace magnetic switch.
Failure of returning action in ignition switch Replace.
CAUTION:
Each test must be performed within 3 – 5 seconds to
avoid coil from burning.
NOTE:
Before testing, disconnect lead wire from terminal M.
1. Terminal “S”
2. Terminal “M”
3. Lead wire (switch to motor)

How to use the temperature-corrected state-of-charge
graph
Suppose your S.G. reading is 1.28 and the battery temperature is
–5 °C (23 °F). Locate the intersection of the –5 °C line and the
1.28 S.G. line.
The intersection is within the “A” zone (shaded area in the graph)
and that means CHARGED STATE.
To know how much the battery is charged, draw a line parallel to
the zone demarcation line and extend it to the right till it meets
with the percentage scale. In the present example, the line meets
at about 85% point on the percentage scale. Therefore, the bat-
tery is charged up to the 85% level.
Generator
Trouble in charging system will show up as one or more of follow-
ing conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow cranking or
indicator dark.
3) An overcharged battery as evidenced by excessive spewing
of electrolyte from vents.
Noise from generator may be caused by a loose drive pulley,
loose mounting bolts, worn or dirty bearings, defective diode, or
defective stator.
FAULTY INDICATOR LAMP OPERATION
CAUTION:
Do not mistake polarities of IG terminal and L terminal.
Do not make a short circuit between IG and L termi-
nals. Always connect these terminals through a lamp.
Do not connect any load between L and E.
When connecting a charger or a booster battery to
vehicle battery, refer to this section describing battery
charging.
B: Generator output (Battery terminal)
E: Ground
IG: Ignition terminal
L: Lamp terminal
Condition Possible Cause Correction
Charge light does not
light with ignition ON
and engine offFuse blown Check fuse.
Light burned out Replace light.
Wiring connection loose Tighten loose connection.
IC regulator or field coil faulty Check generator.
Charge light does not go
out with engine running
(battery requires fre-
quent recharging)Drive belt loose or worn Adjust or replace drive belt.
IC regulator or generator faulty Check charging system.
Wiring faulty Repair wiring.
