Peterbilt Starter Interrupt Relay

By | December 20, 2022



When it comes to keeping your Peterbilt truck running as smoothly as possible, a starter interrupt relay is an essential component. The starter interrupt relay prevents the starter motor from receiving power, thus preventing the engine from starting, unless the proper key code is used. This helps keep your truck secure and efficient by allowing only authorized personnel to start the engine.

The starter interrupt relay works by receiving a signal from the key-fob or key-code reader when the proper code is presented. It then sends a signal to the starter motor to start the engine. If the proper code is not received, the relay will not activate, thus keeping the engine from being started. This makes it difficult for a thief to hotwire your truck, as the engine would not turn over without the proper key-code.

Additionally, the starter interrupt relay can be programmed to provide a timer mode that prevents the engine from running past a certain amount of time. This can be set on a timer so that the engine is shut off automatically if it has been running too long, ensuring the engine does not overheat and creating a safer environment for drivers.

Overall, the starter interrupt relay is an important component when it comes to protecting your Peterbilt truck and ensuring it runs as smoothly and efficiently as possible. With its key-code protection and timer mode, it helps secure your truck while providing a reliable engine operation.
