PREHEAT CIRCUIT (KEY SWITCH: HEAT)
When the key switch is turned to the HEAT position, terminal B is connected to terminal R1 in the key switch.
Current from terminal R1 excites the glow relay.
Battery power is supplied to the glow plug from the glow relay through the fusible link (100A).
While the glow relay is excited, the pre-heating is carried out as the power is supplied to the glow plug from the glow relay.
While the pre-heating is carried out, the glow plug relay is ON so that current is supplied to the monitor unit and lights the preheat indicator.
Even if the pre-heating is not carried out, the preheat indicator lights for 2 seconds in order to check the indicator bulbs.
