Service bulletin RSB 506

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 Corporation has decided that a defect relating to motor vehicle safety exists in specific motorhomes. Issue: On certain motorhomes, there may be a loose electrical connection to the automatic transfer switch (ATS) that was not properly tightened. If the power connection is loose, it may result in a buildup of heat at the connection, which may increase the risk of fire causing injury and/or damage to property.
