FAQ

Based on the available product information, this 4-terminal, 12-volt starter solenoid is listed as compatible with John Deere 110 applications and certain Ford F150, F250, and F350 applications. Because fitment can vary by year, engine, and wiring layout, match the terminal count, voltage, mounting style, and part number before ordering.
This solenoid is associated with part numbers SS598T, STS1, SS4, and SS598. Verify the number stamped on your original solenoid or confirm by equipment model and wiring configuration.
Common symptoms include a single click with no cranking, intermittent starting, no response when the key is turned, or a starter that stays engaged longer than it should. In some cases, the solenoid may have burned or corroded terminals causing voltage drop to the starter.
Yes. The listing identifies this as a 12-volt starter solenoid with 4 terminals. Before installation, compare the terminal arrangement on your original part, since two solenoids can both have 4 terminals but use different post labeling or bracket orientation.
Replacement is usually a straightforward repair if the solenoid is easily accessible. Typical installation involves disconnecting the battery, labeling and removing the wires, unbolting the old solenoid, and installing the replacement in the same orientation. Basic hand tools such as wrenches or a socket set are usually enough, and the job often takes about 15 to 30 minutes.
Before replacing it, check the battery state of charge, battery cable condition, terminal corrosion, chassis ground, and voltage at the solenoid trigger terminal when the key is turned. Many no-crank problems are caused by weak batteries, poor cable connections, or a faulty ignition switch rather than the solenoid itself.
Starter solenoids often fail from heat, internal contact wear, moisture intrusion, corrosion at the terminals, or repeated high-current arcing during starting. On older trucks and equipment, loose cable connections and low battery voltage can also shorten solenoid life by forcing it to operate under poor electrical conditions.
