A healthy start winding test result would show:

• A. Continuity with a low resistance value
• B. No continuity
• C. Infinite resistance
• D. Very high resistance

Answer: (A)

Testing the start winding is about confirming there is a good electrical path and that the coil’s resistance is within the expected range. A healthy start winding will show continuity, meaning the ohmmeter detects a closed circuit through the winding. The resistance should be a finite, reasonable value—not open and not effectively zero. This indicates the coil is intact and capable of drawing current to create the starting torque. If there’s no continuity or the resistance reads as infinite, the winding is open and won’t function. If the reading is abnormally high, it already indicates degradation or a weak winding; if it were very close to zero, that could point to a short. So the correct result—continuity with a relatively low, spec-appropriate resistance—signals the start winding is healthy.
