This starter solenoid is compatible with various Jeep models, including Cherokee, Comanche, Scrambler, Wagoneer, and Wrangler. It is used to control the high current flow to the starter motor, enabling engine ignition. Common issues this solenoid can help resolve include:

Installation Notes and Tips

When installing the Standard Ignition SS-590 starter solenoid, ensure the vehicle battery is disconnected to prevent electrical shorts. Verify that the four male screw terminals and connectors match your Jeep's wiring harness configuration. Use the included hardware to secure the solenoid firmly in place. Avoid continuous duty operation as this solenoid is designed for intermittent use during engine starting. Proper torque on terminal screws will help maintain solid electrical contact and prevent loosening over time.
