How To Remove Starter Relay

Information technology would exist impossible to start a vehicle normally without the use of the starter relay. Yet, this of import component is often overlooked until information technology no longer works.

If you are having trouble starting your car, it could be due to this part. We look at the symptoms of a bad starter relay, the office information technology performs, its location, and the cost to replace it. Get-go, let'southward take a quick overview of the signs to expect for:

The well-nigh common symptom of a bad starting relay is that your car does not start or has intermittent starting problems. In some cases, your starter motor may remain on while the engine is running if the ignition relay is bad. You tin can sometimes also hear clicking sounds when yous plow the key.

Here is a more detailed list of the most common symptoms of a bad starter relay:

Bad Starter Relay Symptoms

i. Vehicle Won't Beginning

Typically when the starter relay dies, the most obvious symptom is that the car won't outset. Even when using electronic keys, it's possible that the problem is the starter relay. Because these keys don't apply a manual ignition switch, the starter relay is still activated when the push button is pushed.

Whether y'all are turning the fundamental or pressing a push, when the vehicle won't start, it could be the starter relay. Most oft, information technology's due to the failed circuit that prevents the ignition organisation from engaging.

2. Starter Remains On With the Engine Running

Later on you start the car, you either release your primal or cease pressing the push. At this time, the circuit is supposed to close and everything should continue running as normal. This airtight circuit removes all power from the starter motor.

However, when the main contacts of the starter relay become welded together, it can stay stuck closed. You will know this happens because the starter stays activated fifty-fifty though the engine is running. Y'all will know this is occurring based on the whining noise you should hear.

If the starter relay remains stuck on, further damage is going to occur to other components. Not only will this trouble impairment the relay, but it could also impairment the excursion, starter and transmission flywheel.

three. Intermittent Starting Issues

When the starter relay works equally it should, it sends power to the starter every time yous engage it. However, this part can become contaminated from debris, clay and excessive heat. These conditions tin can force the starter relay to piece of work intermittently.

If you start the vehicle and information technology doesn't activate right abroad, but y'all attempt it again and it works, it might be the relay going bad. Thankfully, y'all are getting a warning that the starter relay is going bad, assuasive y'all time to get it fixed before you lot are stranded.

If the relay itself isn't going bad, it'south also possible that at that place's a faulty wire connection or one that has become corroded nether the hood.

4. Clicking Sounds

You might hear clicking noises when the car battery is low on amperage, but it could as well exist a sign that the starter relay is going bad. It happens when the relay can't send out the full signal.

Most times, the relay operates on an all or cypher basis. It's either going to ship the complete electrical current or it won't send anything. However, when the starter relay becomes damaged, it's possible that only a partial point gets sent. This is what leads to a clicking sound when y'all try to plow the key.

The Role of a Starter Relay

The starter relay is responsible for sending high amperage to the starter motor through a low-amp excursion. This relay is responsible for powering up the starter solenoid, which requires high amperage to run.

This amount of amperage isn't safe to run through the ignition switch, but it must be powered whenever the switch turns to "Outset." A relay acts every bit a bridge and has been used in cars for decades.

When the ignition switch is turned to the commencement position, the electric power gets sent from the switch to the starter relay. There is two circuits within the starter relay. One excursion is used to receive the signal from the switch and it keeps the other circuit closed during this time through electromagnetism.

With this ane excursion closed, ability is flowing from the car bombardment to the starter. When the ignition switch is released, electric ability ceases to the first circuit, forcing the electromagnet to open the excursion and turn off the starter.

When the relay loses power from the switch, the circuit remains open and asunder, and your automobile will not start.

Starter Relay Location

The starter relay is well-nigh ofttimes located under the automobile hood, found in the power distribution center. It can also be located in the fuse block in the cabin.

The relay has wires coming in and out of it. Withal, there are many other relays used in the car that expect similar. If yous are unsure which one is the starter relay, reference your service manual.

Starter Relay Replacement Toll

The average starter relay replacement cost is between $50 and $75, depending on the car model and labor costs. The starter relay parts should cost you around $twenty, with the labor cost at $thirty to $55.

Replacing a starter relay is a elementary chore that doesn't crave any specialized tools. If you are handy, y'all might prefer saving yourself some money and swapping out the starter relay yourself.
