Charge
The lamp lights up when the ignition key is set
to the "ON" position before the engine starts. It
turns off when the engine starts and the
alternator starts operating properly.
When the ignition key is set to the "ON"
position before the engine starts, the alternator
IG-terminal (yellow) is energized and the L-
terminal (brown = charger lamp ground) is
grounded through internal circuit of the
alternator and the lamp lights up.
After normal operation, the internal circuit
ground for L-terminal is disconnected and the
lamp turns off.
Grounding is connected to the engine block.
If the charge lamp lights up during the engine
running, a failure in charging may occur due to
malfunction of the alternator drive belt or the IC
regulator inside of the alternator, etc.

Thermo-start
When the ignition key is set to the "GLOW"
position, it illuminates as the glow plug
generates heat.
Illumination time of the thermo-start lamp is
controlled by the glow lamp timer, and the lamp
is turned off after a specified amount of time
passes.
The duration of illumination indicates an
approximate period of time required for warm-
up, and has been fixed at five seconds.
Engine Oil Pressure
The lamp turns on when the ignition key is set
to the "ON" position before the engine starts. It
turns off when the engine starts and engine oil
pressure is generated properly.
It is connected to an oil pressure switch located
in the engine block (beside the oil element) and
lights up if the oil pressure drops during
operation.
