2) Ground F terminal and start engine, then measure voltage at
B terminal as shown in left figure.
Voltage is higher than standard value
It is considered that generator itself is good but IC regulator
has been damaged, replace IC regulator.
Voltage is lower than standard value
Generator itself has problem, check the generator.
Load Check
1) Run engine at 2,000 rpm and turn on head light and heater
motor.
2) Measure current and if it is less than 20 A repair or replace
generator.
OVERCHARGED BATTERY
1) To determine battery condition, refer to Battery section.
2) If obvious overcharged condition exists as evidenced by
excessive spewing of electrolyte, measure generator B ter-
minal voltage at engine 2,000 rpm.
3) If measured voltage is higher than upper limit value, proceed
to disassembly section of generator service.
4) Check ground of brushes. If brushes are not grounded,
replace IC regulator. Then check field coil for grounds and
shorts, referring to “INSPECTION” section.
On-Vehicle Service
Battery
Jump starting in case of emergency
WITH AUXILIARY (BOOSTER) BATTERY
Both booster and discharged battery should be treated carefully
when using jumper cables. Follow procedure outlined below,
being careful not to cause sparks.
CAUTION:
If vehicle is manual transmission model and has a cata-
lytic converter, do not push or tow it to start. Damage to
its emission system and/or to other parts may result.

1) Set parking brake and place automatic transmission in
PARK (NEUTRAL on manual transmission). Turn off ignition,
turn off lights and all other electrical loads.
2) Check electrolyte level. If it is below low level line, add dis-
tilled water.
3) Attach end of one jumper cable to positive terminal of
booster battery and the other end of the same cable to posi-
tive terminal of discharged battery. (Use 12-volt battery only
to jump start engine).
4) Attach one end of the remaining negative cable to negative
terminal of booster battery, and the other end to a solid
engine ground (such as exhaust manifold) at least 45 cm (18
in.) away from battery of vehicle being started.
5) Start engine of vehicle with booster battery and turn off elec-
trical accessories. Then start engine of the vehicle with dis-
charged battery.
6) Disconnect jumper cables in the exact reverse order.
WITH CHARGING EQUIPMENT
WARNING:
Departure from these conditions or procedure
described below could result in:
–Serious personal injury (particularly to eyes) or
property damage from such causes as battery explo-
sion, battery acid, or electrical burns.
–Damage to electronic components of either vehicle.
Remove rings, watches, and other jewelry. Wear
approved eye protection.
Be careful so that metal tools or jumper cables do not
contact positive battery terminal (or metal in contact
with it) and any other metal on vehicle, because a short
circuit could occur.
WARNING:
Do not connect negative cable directly to negative termi-
nal of dead battery.
CAUTION:
When jump starting engine with charging equipment, be
sure equipment used is 12-volt and negative ground. Do
not use 24-volt charging equipment. Using such equip-
ment can cause serious damage to electrical system or
electronic parts.

Dismounting
1) Disconnect negative cable (3).
2) Disconnect positive cable (2).
3) Remove retainer (5).
4) Remove battery (1).

Handling
When handling battery, following safety precautions should be
followed:
Hydrogen gas is produced by battery. A flame or spark near
battery may cause the gas to ignite.
Battery fluid is highly acidic. Avoid spilling on clothing or
other fabric. Any spilled electrolyte should be flushed with
large quantity of water and cleaned immediately.
Remounting
1) Reverse removal procedure.
2) Torque battery cables to specification.
