Standard Ignition SS-393 Starter Solenoid

Starter Solenoid for Mitsubishi and Dodge Applications

The Standard Ignition SS-393 starter solenoid is a 12-volt electrical replacement built for starting system service on select Mitsubishi and Dodge vehicles. It uses heavy-duty copper contacts, pure copper windings, and low-resistance terminal materials to help deliver strong current flow to the starter.

• 12-volt starter solenoid for starting and charging system repair
• Heavy-duty copper contacts help reduce arcing and contact wear
• 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
• Pure copper battery terminal studs help lower resistance in hot operating conditions
• Female round connector with male stud-and-blade terminals
• Black and gold finish with dichromate and plastic construction

Detailed Product Overview

Standard Ignition SS-393 is a starter solenoid for vehicles that need reliable starter engagement and consistent electrical transfer. The internal copper contact design and solid contact bolts are intended to support full battery power delivery to the starter while helping protect the circuit from electrical overload. This makes it a practical replacement for Mitsubishi 3000GT, Mitsubishi Diamante, Dodge Stealth, Dodge Caravan, and Dodge Grand Caravan applications listed below.
