7. Motor Circuit Testing
Using a digital volt-ohmmeter (VOM), measure the resistance across the compressor
windings as shown in Figure 40. The power leads to the compressor must be
disconnected before taking an electrical measurement. A good rule of thumb for single
phase compressors is that start winding resistance (R
2
) is 3 to 5 times greater than run
winding resistance (R
1
).
