Product Overview
The shutdown solenoid moves the fuel-control mechanism between run and stop positions. Electrical or mechanical failure can produce a no-start, intermittent shutdown or an engine that will not turn off normally with the key.
Research for this family identifies common references 3991624 and SA-4959-12 and a three-terminal, continuous-duty style used on several Cummins B-series industrial applications. The bracket, linkage/rod and connector must match the existing installation.
