Service bulletin TSB190225-021920

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

This Technical Service Bulletin describes the verification and resolution to an issue that arises when a C100D2RE generator set is attempted to parallel with a C150, C200 or C275 generator set. When this occurs the B+ on the two units short with each other and the temperature of the paralleling cable rises. This is an update to a previously submitted communication.
