Service bulletin TSB 492

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Newmar changed the breaker box wiring and updated the SilverLeaf TM250 Load Management Module to help balance the electrical loads in 2018 New Aire Diesel Pusher coaches. Some coaches may have been shipped without the change being performed. This is not a safety issue; however, making the updates will enhance the coach?s electrical performance when operating high amperage loads.
