Sprinter engine battery failed and Fusion “confusion”
After three years our engine battery would no longer hold a charge. It was replaced in Pensacola at the Mercedes dealer who was very gracious and got us into their booked up schedule.
Mercedes did a battery diagnosis and determined the battery was pooched. It also diagnosed a 1.1 amp parasitic draw on the battery but the source wasn’t located due to time constraints. For now they recommended we use the battery disconnect by the gas pedal whenever we stop for an extended time until the load is determined. Mercedes suggested that it was not a Mercedes cause but an add on from Airstream.
Coincidently there has been an unusual thing happening with the Fusion System. When we are on shore power and the battery is disconnected, every time the transfer switch changes and the inverter goes into a charging cycle the Fusion turns on ??? even though we always shut the radio off and hit the power button twice. It happened three or four times last night. It seems that once a charge cycle starts it sequences the whole electrical system.
Has anyone experienced this or have suggestions.
