Bulletin Summary
Airstream has discovered that early 2021 Model Year units were shipped with Magnum MMS1012-G Inverter/Charger's designed for AGM batteries, instead of the proper âLâ series inverters designed for use with lithium batteries. While the incorrect inverters are not harmful to the lithium batteries, the affected vehicles would not be getting maximum charging to the batteries. This procedure is set up to make sure the proper MMS1012-G âLâ Series inverters are installed, and if not, it outlines the process for swapping out the inverter.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
