7.1 Testing the motor
Requirements:
• digital multimeter with resistance measurement
• Remove the rear panel as described in Chapter 8.1.1.
• Pull the motor plug (1) out of the power module.
•
• Connect the digital multimeter to the motor plug contacts (3) and measure the resistance
between the contacts.
Note
A resistance of between 0.5 and 5 ohms indicates a motor ready for operation.
A resistance of between 15 ohms and infinity indicates a defective motor. High resistances are
normally caused by bad connections or worn carbon brushes.
