POWER MIRROR SYSTEM SYMPTOM CHART

NOTE: The batteries must be fully charged and all connections clean and tight. Use a multimeter (DVOM) for
these tests. For battery testing and service, see the battery section in the service manual.
DO NOT use a self-powered test light for any of these tests. Use of a self-powered test light can cause
damage to components in this system.
Before performing any of the electrical tests, be sure all operating controls are in neutral or park lock
position. This will eliminate accidental movement of the machine or start-up of power driven equipment.
