Product Overview
A shutdown solenoid moves the fuel-control linkage when the key or stop circuit is activated. A sticking plunger, weak coil or damaged linkage can cause a diesel engine to refuse to stop, fail to start because the rack remains in the stop position, or shut down intermittently as vibration changes the solenoid position.
Research on the 1752ES/32A87 family shows several closely related Mitsubishi and Bosch RSV references. The mounting pattern, linkage travel, connector and voltage should be compared with the removed unit because visually similar stop solenoids are sold in both 12- and 24-volt versions.
