Question

When testing a compressor with an ohm meter, a technician read 2 ohms between the start terminal and the case of the compressor. The technician should conclude:

Answer 1

Answer:

That there is a grounded winding

Explanation:

When the ohm meter is set to the maximum range, and a meter lead is placed on the compressor casing. A reading of any value on the ohm meter is an indication that the winding is grounded in which case it would be necessary to change the  compressor

The compressor terminals are covered with a shroud making it difficult to take measurements. To make it easier, the plug can extended with an extension wire.
