Service bulletin FS-2020-03

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.

During the review of the coolant level sensor circuit in some buses, it was determined that the 10 Amp circuit breaker currently utilized in this circuit is above the recommended circuit protection for this device. Gillig recommends installing an inline 4amp fused jumper harness for proper circuit protection.
