In assessing the resistance measurement you would expect between leads 1 and 9 for a motor, a reading between 1 and 5 ohms indicates a low resistance typical of windings within motors. This low resistance is significant as it suggests that the motor windings are healthy and the electrical paths are intact without significant interruptions or short circuits.

Higher resistance values, such as those in the ranges of 0.2 to 20 ohms, 5 to 25 ohms, or 10 to 15 ohms, could indicate potential issues with the motor, such as damaged windings or a poor connection, which are not typical for well-functioning motors. The expected resistance in the range of 1 to 5 ohms aligns with standard motor characteristics, where the winding resistance should be relatively low, allowing sufficient current to flow when the motor is in operation.
