5. ELECTRICAL COMPONENTS
5.1 DISPLAY UNIT
The display unit is installed to the relay bracket un-
der the hood.
1. Hour meter operation:
If the alternator in the vehicle operates normally to
produce voltage of more than 13.5 V, the display
unit supplies current to the hour meter on the in-
strument cluster to operate the meter.
2. Speedometer operation:
It operates the speedometer on the instrument clus-
ter by receiving waveform signals from the speed
sensor which is mounted on the gear box.
3. Automatic preheat control:
When the coolant temperature is below 30˚C (86˚
F), it operates the preheat relay to control the pre-
heat operation as well as the preheat indicator on
the instrument cluster. When the ignition switch is
turned to the “ON” position, the preheat indicator on
the instrument cluster comes on 8 seconds and the
preheat relay is operated for up to 15 seconds to
preheat the engine. The preheat operation is com-
pleted when the ignition switch is turned to the “ST”
position and then released. Then, immediately, the
post-heating operation is performed for 15 seconds.
Therefore, the preheat time can be less than 15
seconds on occasion while the post-heating time is
always 15 seconds.
4. Preheat system protection:
If the voltage becomes over 16 V, the preheat and
post-heating operations are stopped to protect the
preheat system.
5. Manual preheating:
W h e n t h e i g n i t i o n s w i t c h i s t u r n e d t o t h e
“HEAT(GLOW)” position, between the “ON” and
“ST” positions, and held in that position, the display
unit operates the preheat relay and preheat indi-
cator on the instrument cluster to heat the engine
manually.
FUNCTION
6. Stop solenoid pull-coil operation:
When the ignition switch is turned to the “ON” posi-
tion to start the engine, the display unit operates
the pull coil (32 A) for 1 second to pull the stop so-
lenoid. As the stop solenoid is pulled, the injection
pump rack in the engine is moved from the stop po-
sition to the engine starting position. Once the stop
solenoid is pulled, it is held in the fuel supply status
by the hold coil (0.77 A) which is powered directly
by the ignition switch.
7. Cooling fan operation:
When the coolant temperature sensor detects the
coolant temperature over 80 degrees, the cooling
fan relay is operated to operate the cooling fan.
When the coolant temperature drops below 75 de-
grees, the relay is stopped. The 5-degree difference
between the activation and deactivation tempera-
tures is set to protect the cooling fan from turning
“ON” and “OFF” too frequently.
