* Place starter switch at ON and
check if current flow to terminal
5 of timer is in accordance.
Current f low: 120 seconds
Pre-heating Duration Differs from the Specified
Duration.
OK
No
Voltage
Timer is faulty and should be replaced.
*After completion of pre-heating,
check for voltage at terminal 5
again when starter switch is placed
at START.
No
Voltage
Voltage
Starter switch OFF.
*Place starter switch at ON and
check for voltage to glow plug a
few seconds later. Thereafter, volt-
age should drop about 1/2.
No

*Check for battery voltage at negative (-) side of glow
plug resistor.
If no voltage, No.1 glow plug relay is faulty and
should be replaced.
OK
*Check for battery voltage to positive ( + ) side of glow
plug resistor.
If okay, replace the resistor.
If no voltage, No.2 glow plug relay is faulty and
should be replaced.
