What happens when I turn the starter solenoid?
Otherwise, there would be some kind of action happening, even if it doesn’t start the car, that would denote other issues. For example, when the starter solenoid is bad, it usually gives off a “clicking” sound as the power enters it from the battery and gets sent straight to ground instead of turning the starter.
How does a key turn work on a starter motor?
The key turn completes a small circuit that tells the battery to release power to the starter solenoid. The solenoid ramps up the power given to it and that power causes the starter motor to turn very quickly.
Can a bad ignition switch cause a starter relay to fail?
Although it’s unlikely that you’ll ever experience a problem with the starter relay, it is prone to mechanical failure and will need to be replaced by a professional mechanic if it wears out. Most of today’s modern cars and trucks have an electronic ignition switch that is activated by remote key.
How does a relay and solenoid work together?
Both a relay and a solenoid are devices that receive a low-power signal as a trigger to close (or sometimes open) a much larger circuit with more power. In the case of a starter, the ignition switch signals the relay/solenoid (possibly by way of a computer) and the relay/solenoid switches on the starter circuit to engage the starter.
Where is the solenoid on a car starter?
The starter solenoid is located on top of the starter. When you turn the key, it is the starter solenoid that pushes a plunger inside the starter motor, pushing the pinion towards the flywheel. Use a jumper wire to ground the solenoid to a bolt. Start the ignition and listen for sounds coming from the solenoid.
When does a solenoid need to be replaced?
Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient.
Can a bad starter relay be a solenoid problem?
Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient. They can also be hazardous and can cause damage. If you run into symptoms of a bad starter relay or solenoid with your car, truck, or SUV, make sure to have a trusted technician to diagnose the specific problem.
