The Standard Ignition SS 547A Starter Solenoid is a 12 volt 3 terminal component designed for direct fitment in various vehicles including models like the 1956 International S110 and 1955 GMC 250 22 This solenoid serves as a crucial intermediary between the ignition switch and the starter motor ensuring reliable engine starting by transmitting full battery power to the starter Constructed with heavy duty copper contacts the SS 547A minimizes arcing thereby extending the solenoid s operational lifespan The use of pure copper windings enhances the magnetic field strength facilitating efficient current flow Additionally the solenoid features polyester insulated magnet wire cadmium plated copper discs and solid contact bolts all of which work together to reduce voltage drop and protect against electrical overloads The inclusion of pure copper battery terminal studs further decreases resistance allowing higher current flow even in high temperature environments These design elements collectively contribute to improved performance and durability addressing common issues such as starter motor failure due to electrical inefficiencies By integrating the SS 547A Starter Solenoid into your fleet s vehicles you can expect enhanced starting reliability and reduced maintenance costs leading to increased operational uptime and overall fleet efficiency
