Standard Ignition SS-306 Starter Solenoid

Starter Solenoid for OE-Style Starting Performance

The Standard Ignition SS-306 starter solenoid is a 12-volt electrical replacement built for vehicles that need reliable starter engagement and consistent current transfer. It is a direct-fit style solution for select Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac applications, including Mitsubishi starter setups used in several of those models.

With heavy-duty copper contacts, pure copper windings, and low-resistance terminal construction, this starter solenoid is built to reduce voltage drop and deliver full battery power to the starter. The SS-306 is a practical choice for diagnosing hard-start conditions on vehicles such as the Buick Century, Cadillac DeVille, and Pontiac 6000.

• Polyester-insulated magnet wire and cadmium-plated copper discs support lower voltage drop
• Pure copper battery terminal studs reduce resistance in high-heat environments
• 3-terminal design with stud and blade connections
• Female round connector, male terminals, black and gold finish
• Hardware included for installation

Detailed Description

Standard Ignition SS-306 is engineered for starting and charging system repair where dependable solenoid operation matters. Its copper contact design, solid contact bolts, and copper terminal studs help maintain current flow from the battery to the starter while protecting the circuit from electrical overload. This makes it a strong OE-style replacement for select 1982-1985 Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac vehicles, including applications listed for Mitsubishi starter systems. The SS-306 part number is also referenced in cross-application catalogs for related starter service, and SS-306 is commonly searched by technicians working on Buick Century, Cadillac Fleetwood, and Oldsmobile Cutlass Ciera starting issues.

What It Helps Solve

• No-crank or intermittent crank conditions caused by solenoid wear
• Starter engagement problems from high resistance at the contacts
• Voltage drop between the battery and starter motor
• Heat-related starting complaints in demanding electrical environments
• Electrical overload concerns in aging starting circuits

Installation Notes and Tips

• Verify the connector style, terminal count, and voltage before installation.
• Confirm the vehicle’s starter application and OE reference numbers against the existing unit.
• Inspect battery cables, starter leads, and grounds before replacing the solenoid.
• Clean mounting and terminal surfaces to support proper current transfer.
