Starter Relay (Starter Solenoid), 66-77 Ford Bronco SKU: 6039

Early Bronco Starter Solenoid

This is a high quality and reliable replacement for the standard Ford starter relay found on early Broncos. Commonly referred to as a "starter solenoid" these body mounted relays are recommended for use with both stock and even with modern gear reduction mini starters with their integrated solenoids.

A starter solenoid is a crucial component in your Bronco's starting system. Its main job is to act as a bridge between the battery and the starter motor, ensuring your engine gets the power it needs to start up. Here’s how it works:

Engagement of the Starter Motor:

• When you turn the ignition key, the starter solenoid receives a small electrical signal from the ignition switch. This signal triggers the solenoid, which then closes a larger circuit that connects the battery to the starter motor.

Power Transfer:

• Once the circuit is closed, the solenoid allows a large amount of current from the battery to flow directly to the starter motor. This power is what drives the starter motor to crank the engine, getting it to start.

Solenoid as a Relay:

• The solenoid acts like a relay, handling the high current required to start the engine. This is important because the ignition switch alone can't handle that amount of current without overheating or getting damaged.

Common Issues:

• Clicking Sound: If you hear a clicking sound when you try to start your vehicle, it often means the solenoid is receiving the signal but isn't engaging the starter motor properly. This can happen due to a weak battery, corroded connections, or a failing solenoid.

• No Start: If the solenoid fails entirely, the starter motor won’t receive power, and your engine won’t start.

In short, the starter solenoid is like the middleman between your ignition key and the starter motor, ensuring your engine gets the power it needs to fire up.
