# Service bulletin SS1034868

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

Service Solution for flickering overhead reading light during slight movement of the steering wheel for New Cascadia with DR 40SI alternators, possibly other alternators as well. The flickering overhead light is considered a nuisance, and can be simply eliminated by either adding an accessory to one of the power receptacles, or running an additional ground in one of the sleeper bunk lamps to suppress the ripples on the circuit.
