The car starter relay, also known as a starter solenoid, controls the high-current electrical circuit that activates the starter motor during engine starting. It allows the battery to deliver sufficient power to the starter motor while protecting the vehicle’s ignition system. Starter relays are commonly replaced when vehicles experience intermittent starting issues or electrical contact failures within the automotive starting system.
• Operating Voltage: 12V (typical passenger vehicle systems)
• Contact Type: Normally open (NO)
• Mounting Style: Bracket or integrated housing (varies by model)
• Electrical Connection: Blade terminals or threaded studs
• Insulation Material: Heat-resistant engineering plastics
• Suitable for a wide range of passenger vehicles across Asian, European, and American platforms.
• Common applications include compact cars, sedans, SUVs, and light commercial vehicles.
• Each starter relay is electrically tested for coil resistance, contact response, and load stability to ensure consistent starting performance and reliable operation throughout its service life.
