Standard Ignition SS-590 Starter Solenoid - Fender Mounted

Starter Solenoid for Jeep Applications

The Standard Ignition SS-590 starter solenoid is a 12-volt replacement built for reliable starter engagement in select Jeep vehicles. It is a direct-fit electrical component for fender-mounted and N/A applications on 1983-1987 Jeep models, including Wrangler, Comanche, Wagoneer, Cherokee, and Scrambler.

Standard Ignition SS-590 is engineered with heavy-duty copper contacts, pure copper windings, and low-resistance terminal materials to help deliver full battery power to the starter. This starter solenoid is a practical choice for Jeep Wrangler and Jeep Cherokee starting system service where consistent current flow matters.

Key Features

• 12-volt starter solenoid for starting system repair
• Heavy-duty copper contacts help reduce arcing and extend service life
• More pure copper windings than found on most vehicles for a stronger magnetic field
• Polyester-insulated magnet wire and cadmium-plated copper discs help reduce voltage drop
• Solid contact bolts and pure copper battery terminal studs support higher current flow
• Male round connector design with 4 connectors and 4 screw terminals
• Black housing with included hardware

Detailed Description

The SS-590 starter solenoid is built for dependable electrical transfer between the battery and starter motor. Standard Ignition uses copper-rich internal construction and low-resistance terminal materials to help maintain current flow, reduce voltage loss, and improve protection against electrical overload. For Jeep Wrangler, Jeep Comanche, Jeep Wagoneer, Jeep Cherokee, and Jeep Scrambler starting system repairs, this solenoid provides the electrical switching function needed to engage the starter under load.

This part cross-references Spectra Premium ST96 and Focus Auto Parts 84004 for the same application.

What It Helps Fix

• No-crank or intermittent crank conditions
• Starter engagement problems caused by worn solenoid contacts
• Voltage drop between the battery and starter
• Hard starting related to poor current transfer
• Electrical resistance issues in the starting circuit

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. This unit uses male round connectors, male screw terminals, and is listed for fender-mounted and N/A positions depending on application. Confirm 12-volt system compatibility and inspect battery cables, starter leads, and grounds during service to avoid repeat starting faults.
