Charge
The lamp lights up when the ignition key is set
to the "ON" position before the engine starts.
It blacks out 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 blacks out.
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 in the "GLOW"
position, the glow plug generates heat and at
the same time the thermo-start lamp turns on.
The thermo-start lamp is controlled by the
glow lamp timer, and turns off after
illuminating for 5 seconds.
The thermo-start lamp illumination time is a
guideline for the time required for warming up,
and is not related to the state of heat
generation of the glow lamp.
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.
