(4) Measure the resistance between the (G) terminal of glow
plug relayand the glow plug plate.
Standard value: 0.14-0.16 n

Caution

Measuretheresistanceaftercheckingthat battery
voltage isnotapplied to the (G) terminal;

(5)Connect the voltmeter between the glow plug plate and
the glow plug body.

(6)Measure the voltage immediately after the ignition switch
isturned to "ON(without starting the engine):

Standard value:9-11V (after approx:2-4 seconds it
drops to OV)

NOTE

Thetime taken for the voltage to drop will vary depending
on the temperature of the glow plugsandthe voltage
applied:(Refer to the reference illustration )

Measure the voltage while the engine is cranking:

Standard value: 4Vormore

(8)Start the engine and measure the voltage while the engine
iswarmingup:However,iftheenginecoolant
temperature increases to 30C or more, or if 30 seconds
have elapsed since the engine was started, the voltage
willnormallybecomeOV .(Refertothereference
illustrationon thenext page:)

Standard value: 5-8V

Reference

Relationship between glow plug temperature (resistance value) and current flow time

Example

When battery voltage is normal (9Vabove)
and the glowplt8szf;are coldeven to heat the
plugs to 900PCmore takes approxi-
mately 3 seconds.

On the other handwhenbattery voltage is nor-
mal (9Vor more) and the glow plugs are hot
[500*C (932'F)] or more, the time taken for cur-
rent to flow is reduced
