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 of the generator set will crank but not start or the generator set will not crank at all. Troubleshooting may lead to the discovery of a failed ignition coil. If the ignition coil is found to be failed, inspect the generator set for proper grounding before replacing the ignition coil. This is a revision to a previously submitted communication.
