| Which of the following methods should be used to test for an 'open' stator winding coil in a wye-connected AC squirrel cage induction motor? |
| A) Use a growler, listening for noise and vibration to increase when over an open coil. |
| B) Test with an ohmmeter, with one test lead on the shaft, and the other test lead to each of the disconnected motor leads in succession and compare the resistances |
| C) Test with an ohmmeter with the test leads across each pair disconnected motor lead leads in succession and compare resistances. |
| D) Use a growler, listening for noise and vibration to diminish when over an open coil. |
