The Starter Solenoid is the relay of the starting circuit that carries the high amperage required when the starter motor is engaged. The solenoid is typically energized by the starter switch when commanded by the vehicle operator. Starter solenoids may also be used in other high amperage circuits, compare solenoid specification to your circuit needs before installing.

Product Features:

• Application matched component to ensure the system can be returned to like new condition.
• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.

The starting system consists of the rotating electrical motor and solenoid which may be mounted on the starter motor or mounted remotely. The electric motor drives a gear which engages with the engine’s flywheel located at the rear of the motor, when the motor is energized, the motor will turn the engines crankshaft. The starter solenoid is an electric relay, or switch used to provide power to the starter motor or any electrical device that requires high amperage to operate. A low amperage wire winding within the solenoid will create magnetic force when voltage is applies from a remote switch, such as the ignition switch or another type of remote mounted switch. The contacts within the relay carry a high amperage load to run an electric motor or some other type of high load circuit.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.

The Ignition switch is the main power switched distribution point in every vehicle. The ignition switch in some manner will be connected directly to the vehicle battery and then supply power out to every operating system in the vehicle that is required to be connected and disconnected from the vehicle’s battery or power source.

Product Features:

• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the connector terminal design process ensures speed-to-market and a precise connector fit guaranteed.
• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure confidence and product reliability, every time.
