Fastronix Solutions 200A 12V Starter Solenoid — Heavy Duty Ford‑Style with Copper Studs & Universal Mounting

Fastronix Heavy Duty 200A Starter Solenoid is a 12V Ford-style solenoid engineered to deliver up to 200 amps of starting power with rugged copper studs and universal mounting.

This compact starter solenoid by Fastronix Solutions replaces worn or weak starter relays on a wide range of vehicles and equipment. Built to Ford-style specifications, it uses heavy copper main studs and a reliable trigger stud to ensure consistent electrical contact during cranking. The unit accepts standard 1/4" mounting bolts and ships with wiring instructions and a diagram to simplify installation. For a clean, protected connection we recommend pairing it with Fastronix 404-112 terminal covers and 405-012 copper lugs.

How tough is the Fastronix 200A solenoid for repeated starts?

The solenoid is rated for 200 amps at 12 volts and uses 5/16" copper main studs that handle high current without excessive heating. Its Ford-style design has a proven track record in demanding starting cycles, and the trigger stud (#10-32) ensures reliable activation.
