Standard Ignition SS-302 Starter Solenoid

Starter Solenoid for Jeep Starting Systems

Standard Ignition SS-302 is a 12-volt starter solenoid built for Jeep starting system service. It uses heavy-duty copper contacts, pure copper windings, and low-resistance terminal materials to help deliver full battery power to the starter with reduced voltage drop.

Compatible With 1987-1993 Jeep Cherokee, 1993 Jeep Grand Cherokee, 1993 Jeep Grand Wagoneer, 1988-1991 Jeep Grand Wagoneer, 1987-1993 Jeep Wrangler, 1987-1992 Jeep Comanche, 1987-1990 Jeep Wagoneer, 1988 Jeep J10, and 1988 Jeep J20. Standard Ignition SS-302 is a direct-fit electrical replacement for Jeep Cherokee and Jeep Wrangler starting circuit repairs.

Detailed Product Overview

This starter solenoid is engineered for Jeep vehicles that need reliable starter engagement and consistent current transfer. The internal copper-based construction helps maintain electrical flow from the battery to the starter, while the solid contact design supports reduced overload risk in demanding starting conditions. Standard Ignition SS-302 is a practical replacement for Jeep Cherokee, Jeep Wrangler, and other listed Jeep applications where starter relay performance affects crank reliability.

This part cross-references Spectra Premium ST165 for the same application.

Common Starting Issues It Can Address

• No-crank condition when the key is turned
• Intermittent starter engagement
• Clicking at the starter without engine rotation
• Voltage drop in the starter circuit
• Heat-related starting resistance in the solenoid path

Installation Notes and Tips

Verify connector style, terminal count, and 12-volt system requirements before installation. Inspect battery cables, starter leads, and ground connections at the same time, since poor connections can mimic solenoid failure. Confirm the vehicle’s original mounting and wiring layout against the listed Jeep fitment before final assembly.

Quality Assurance

Standard Ignition manufactures starting and charging system components with controlled production from individual parts through finished assembly. SS-302 uses high-grade materials selected for electrical performance and service life in OE-style replacement applications.
