Use this free interactive diagnostic tool to identify the root cause of diesel generator speed regulation faults. Whether your genset is hunting, surging, failing to synchronise, or tripping on reverse power, this 5-step guide walks you through a structured fault-finding process covering governor types, synchroscope interpretation, CAN bus J1939 communication faults, and engine condition analysis.
The tool supports marine gensets, STOR (Short Term Operating Reserve) generators, and industrial standby sets from major OEMs including Perkins, Cummins, Caterpillar, MTU, Volvo Penta, and Scania. It covers electronic governors (EGOV, PID, ECU-integrated CAN J1939), mechanical-hydraulic governors, and speed controllers including ComAp InteliGen, Deep Sea Electronics DSE, Woodward EasYgen, and DEIF AGC.
At the end of the diagnostic process you will receive a prioritised fault report with recommended corrective actions. You can download the report as a PDF or contact Ashmit Engineering directly for expert on-site or remote support. For background reading, see our guide to genset speed regulation and governor faults.
