Checking Components For Proper Operation - Electrolux Talkie Service Manual

11.2 Checking components for proper operation

To make it easier to check components, a TEST PROCEDURE has been developed which indicates the
points where tester probes should be applied and the correct theoretical value for each component.
Access the electronic board positioned on the basement and detach all the connectors.
Connect the probes of the tester to the appropriate points. Compare the electric resistance reading with
the value shown on the table
Measurement points on circuit board wiring connectors:
