How to Fix a Stuck Starter Solenoid

One of the most frustrating things about owning a car is when it won’t start. The starter solenoid is a common problem in older cars. It’s even more frustrating if you’re on your way to work and you can’t get going, or worse yet if it happens when you’re in the middle of nowhere. When the starter solenoid fails, it can be for a number of reasons. The most common reason is that the electrical connection to the starter solenoid has come loose. This can happen over time as the wires age and loosen.

Luckily there are a few things you can do to fix this problem yourself without having to take your vehicle into an auto shop. This blog post will show you how to fix a stuck starter solenoid of your car. A stuck starter solenoid can be difficult and expensive to replace, so you’ll want to have these tips ready before it happens!

How to Fix a Stuck Starter Solenoid

7 Common Reasons Starter Solenoid Get Stuck

Typically, the starter solenoid gets stuck due to a buildup of rust and corrosion. Corrosion can also cause your starter motor itself to malfunction or even fail. Other issues could potentially cause this problem as well. Here is a list of some common reasons why you might have trouble with your car’s starter:

  • The most obvious reason your car’s starter might not work is that your battery is dead. However, before you blame the starter solenoid, make sure that the problem isn’t simply a dead battery! If you’re having trouble starting your vehicle, remove and replace the battery first to see if it fixes the problem.
  • The starter solenoid is simply dirty. By cleaning the area around and underneath your battery, you’ll be able to prevent future problems with your starter solenoid. If you find yourself having to jump-start your vehicle frequently (for example, once a month or more often), then cleaning this area of your car will help avoid needing to do this again.
  • Loose ground wire connections to the battery. If your car’s starter solenoid is getting stuck, it could be because of a loose or corroded bolt that connects your vehicle’s grounding wires to the battery terminals. In addition, if you’ve recently replaced the battery, then check to make sure all of these bolts are tight.
  • If you’re having trouble with your car battery, then a loose connection in the car’s wiring harness may be the culprit behind this problem! While it can be time-consuming to check all of these connections, it will help save you money on auto repairs and ensure that your car is operating maximum efficiency.
  • How about the starter motor itself? If you’re having problems with a car’s starter solenoid, then this might be your problem. Before you check anything else, ensure that everything is connected properly and check to see if there are any loose or corroded bolts in the area.
  • Sometimes, when we jump-start our vehicles, we accidentally connect the positive end of one battery to the negative terminal of another battery. For example, maybe you’re jump-starting a hot rod, and your friend accidentally hooks up the wrong cables to your car.
  • Here’s something you might not have thought about. If your starter solenoid is getting stuck, then it could be because your car’s engine is too hot! If you let your vehicle sit for an extended amount of time (especially in hotter climates), then a buildup of heat can cause this solenoid to overheat and malfunction.

Procedure: How to Fix a Stuck Starter Solenoid 

If you’re having problems with the starter solenoid on your car, then you need to take some steps to fix this problem. This is where you’ll want to have these tips handy so that you can get your vehicle running again! First, check the battery. You may need to jump start it or replace the battery altogether. Next, check the starter solenoid. This is located on the starter motor itself. If the starter solenoid is bad, then you’ll need to replace it.

Step 1:

First, rule out any issues with your battery or connections. If there is a loose connection or your battery has died, you can easily fix this problem with some jumper cables. If all is good with your battery, proceed to step two to check the wiring harness and ensure that everything in this area is properly connected.

Step 2:

Next, check the bolts that connect the starter solenoid to your vehicle’s engine. This is where a wrench will be handy. You’ll want to make sure that all of these connections are tight and can’t come loose while you try to start your car (or else this could cause even more problems). Finally, try to start your car. If the starter solenoid is not receiving power, it may be fried or damaged. You’ll need to replace it before you can drive your car again.

Step 3:

If all of these connections are good, you’ll want to check the wiring harness for anything that may be loose or corroded. How can you do this? You’ll need a screwdriver and then proceed to turn your car on (while it’s in the park). If there is any free play within these wires, this could cause your starter solenoid problems. You’ll want to inspect the wires that are attached to the starter solenoid. To do this, you’ll need to remove the bolts and brackets that hold the wire onto the starter. Check for any corrosion or fraying on these wires.

Step 4:

If you are still having trouble with the starter solenoid on your vehicle, you can check a few other things. First, you’ll want to clean underneath your car and around the area of the battery. Second, if you see any corrosion or build-up of oil, then you’ll want to clean this off so that your wires can work properly!

Step 5:

If you have a bad battery, then it needs to be replaced. All you’ll need is a multimeter (you can find one at most auto parts stores) and then attach the negative test lead to the negative terminal of your battery. Next, attach the positive test lead to the positive terminal of your battery. The multimeter should display a charge of 12.6 volts if your battery has an adequate charge level.

Step 6:

If this is not the problem, then you’ll want to check the starter solenoid itself! Well, to fix any problems with this part, you’ll need to find a shop that specializes in auto parts and do an inspection of the starter solenoid. Maybe there is something wrong with the electrical contacts, or maybe there’s a problem with the flywheel on your car. Either way, you’ll need to take this part off and check it out!

  3. A socket wrench ( sizes L and 1/2 inch)
  4. Wrench set ( sizes M6, 10 mm, and 15 mm)
  5. Insulation tape

Can You Jump a Bad Solenoid?

It depends on the type of solenoid and how bad it is. However, if you are unsure whether or not you can jump a bad solenoid, it is best to consult with a professional.

Can a Bad Solenoid Drain Your Battery?

Yes, a bad solenoid can drain your battery. A solenoid is a type of electrical component that helps to open and close valves. When it fails, the battery will not be able to get the power it needs to start the car.
