● Remove the rear panel as described in Chapter 8.1.2.
● Pull the motor plug (3) out of the electronic module.
● Connect the digital multimeter to the adjacent central motor plug contacts (3) and measure the
resistance between the contacts.
● If there is a defect, replace the motor and send it to Invacare® Service for inspection or repair.
