STARTING SYSTEM (See P.B-79.)
OPERATION
When the ignition switch is turned to the ST position,
the starter contacts (magnet switch) turns ON and
the starter motor starts turning over.TROUBLESHOOTING HINTS
1. Starter motor does not turn over at all.
DCheck starter (coil).
DCheck battery terminals for proper contact.
2. Starter motor does not stop rotating.
DCheck starter (magnet switch).

CHARGING SYSTEM (See P.B-84.)
OPERATION
When engine is stationary
DWhen the ignition switch is turned to the ON
position, current flows the alternator L terminal
and, at the same time, the charge warning lamp
illuminates.
When engine is started and after engine has
started
DWhen the engine is started, the charge warning
lamp goes out because of the charging voltage
begin applied to the alternator L terminal.
DThe battery voltage being applied to the
alternator S terminal is monitored by the voltage
regulator. Therefore, the amount of electricity
produced by the alternator is controlled by
allowing and cutting off the current flowing to
the field coil.
DThe alternator B terminal supplies power to
each load.TROUBLESHOOTING HINTS
1. Charging indicator lamp does not illuminate
when the ignition switch is turned to ON
position, before the engine starts.
DCheck multi-purpose fuse No.(2).
DCheck the bulb.
2. Charging indicator lamp fails to switch off once
the engine starts.
DCheck voltage regulator of alternator.
3. Discharged or overcharged battery.
DCheck voltage regulator of alternator.
4. Charge warning lamp illuminates dimly.
DCheck combination meter diode (for short).

METER AND GAUGE (See P.B-148,152.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge is activated.
DWhen there is much fuel, the unit’s resistance
is small and the current flowing in the circuit
is great, so the gauge’s indicator indicates in
the “Full” area.
DWhen there is little fuel, the unit’s resistance
is high and the current flowing in the circuit
is small, so the gauge’s indicator indicates in
the “Empty” area.

DWhen the ignition switch is at the “ON” position,
the engine coolant temperature gauge is
activated.
DWhen the engine coolant temperature is high,
the unit’s resistance is low and there is a great
flow of current in the circuit, so the gauge’s
indicator indicates in the “H” area.
DWhen the engine coolant temperature is low,
the unit’s resistance is high and there is a small
flow of current in the circuit, so the gauge’s
indicator indicates in the “C” area.TROUBLESHOOTING HINTS
1. Fuel gauge does not operate, or registers
incorrectly.
(1) The fuel gauge indicates “F” when the fuel
gauge unit (sub) connector is disconnected
and the “1” terminal is earthed.
DCheck fuel gauge.
2. Engine coolant temperature gauge does not
operate, or registers incorrectly.
(1) When the engine coolant temperature
gauge is earthed with its connector
unplugged, it registers “H”.
DCheck engine coolant temperature
gauge unit.

CIRCUIT DIAGRAMSB-155
FUEL WARNING LAMP (See P.B-156.)
OIL PRESSURE WARNING LAMP (See P.B-157.)
BRAKE WARNING LAMP (See P.B-157.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge unit resistance is small when
the fuel level is high, and the fuel gauge unit
resistance is large when the fuel level is low.
When this resistance rises above a specified
value, the fuel warning lamp illuminates to notify
the driver that the fuel level is low.

DWhen the lubrication system fails after engine
starting, resulting in the oil pressure failing to
build up, the oil pressure switch turns on
causing the oil pressure warning lamp to
illuminate.

DWhen the brake fluid level goes down below
a predetermined level with the ignition switch
in the “ON” position, the brake fluid level switch
is activated or the parking brake switch is turned
on, causing the brake warning lamp to
illuminate.TROUBLESHOOTING HINTS
1. No warning lamps illuminate.
DCheck multi-purpose fuse No.(2).
2. Some warning lamps do not illuminate.
DCheck lamp valve.
DCheck the switches and the gauge unit.
