THERMOCOUPLE CHECKING
NOTE: The thermocouple may not be repaired. It is located on closing plate of the
cylinder head.
In order to check the thermocouple, there
are necessary : a vessel with cooling liquid(
antifreeze + distilled water ), a
0 – 200 ° C thermometer, a control lamp, a
heat source.
Make an assembly according to the
diagram.
When the temperature of the fluid is low,
the control lamp should be off. If the lamp is
on, replace the thermocouple.
Warm up the fluid in the vessel. When the fluid temperature reaches the temperature required
for the thermocouple contact ( 180 ° C) the control lamp should be lighted.If the lamp does not
light up, replace the thermocouple.
The coupling temperature is marked on the thermocouple body.
