Yes, positive post on the battery in the trunk. Blower on AC was on/off frequently. Sun shade on the roof would not close. Finally no voltage anywhere. Tested by connecting volt meter to the 12v outlet in the ash tray so that i could monitor voltage while driving. DC voltage appeared normal. Set the voltmeter on AC. Normal is about 0.02Volts while driving. If the AC voltage reaches 0.05V AC or higher strange things happen throughout the system,
