Direct Replacement Stop Solenoid — 24V OEM-Spec for Yanmar 4TNV98, 4TNV94 & Hyundai R80, DH150

The stop solenoid is the engine’s kill switch — it cuts fuel flow to shut the engine down safely and completely when the key is turned off or an emergency stop is triggered. On Yanmar 4TNV98 and 4TNV94 engines powering Hyundai R80 and DH150 excavators, a failed stop solenoid means one of two things: the engine won’t start (solenoid stuck closed) or it won’t shut off (solenoid stuck open) — both are serious operational and safety issues on a machine working on a live job site. This direct-fit 24V replacement solenoid (1503ES-24S5SUC12S) restores reliable fuel cutoff function, getting your excavator back to safe, controlled operation.
