Hope it was Helpful!  |
Start is the largest resistance, not Common.
The total resistance between Run and Start should equal the sum of Start to Common and Run to Common.
Example: C to
S = 5 Ohms,
C to
R = 2 Ohms, Then
C to
S = 7 Ohms
Testing for Grounds: Using an Ohmmeter place one probe on a good ground
such as the ground screw on the compressor. The other probe should then be placed on one of the pins as so stated. If you get a reading, the compressor is
grounded.
Testing for open windings: Using an Ohmmeter take the leads and test between any two pins. Reading infinity compressor has
open windings.
Testing for shorts: Using an Ohmmeter, place the leads between any two pins. Reading zero
shorted compressor.
So much for "Compressors 101"
