BMW 135i Car Starter Relay Replacement at your home or office.

What is the Starter Relay all about?

When you turn the key in your car’s ignition, a circuit is completed in the ignition switch. That electrical connection provides power to the starter relay, which then switches from its off position to ‘on’ for as long as the key is held in the start position. The starter relay passes power from the car battery to the starter solenoid, and the starter motor engages to start your car. If the starter relay sticks or fails while it is in the off position, your vehicle will not start or even click when the key is turned, although the interior accessories will still function. If the starter fails while turning the key, and is stuck in the on position, the starter will stay engaged with the transmission flywheel. Damage can occur to the transmission flywheel, the starter, the relay, and the circuit.
