Regulator Inspection
•
Disconnect the connector from the regulator.
•
Set the measurement range of the hand tester to R 1k and
measure the resistance at the areas given in the table below.
•
Although this test is not sufficient to determine the integrity of the
regulator, it will serve as a criterion for making a judgment.
