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:
