How Many Ohms For Starters

How Many Ohms For Starters [Diagnosing Starter Problems]

How can you tell if your starter is failing? What can you do about it? Knowing the basics of how an engine starts is the first step in diagnosing starter problems. A car starter is an important part of the vehicle. It’s a motor that controls other components, which must function properly for the engine to start.

The starter’s resistance should be 0.1 ohms and if it is over 0.3 then you may have a problem with your starter. A good starter for a V-4 engine draws 125A to 150A. The three starter terminals should be checked for good connections to get accurate readings and prevent possible car battery power draw.

Our car won’t tell us that I cannot start for some time, have a starter problem, or guide us to fix the starter problem. So, we will show you how a starter works and the step-by-step instructions that can make you diagnose your car and replace the starter in it.

How Does A Starter Work?

How Does It Work

Before you figure out the issue with your starter, it is best to understand how it works.

When you switch the ignition to “run,” the engine turns over, allowing it to take in air. A flexplate/flywheel is attached to the end of the engine’s crankshaft, with a ring gear around the edge. On the starter, there’s a gear that fits into the ring gear’s grooves.

The starter motor is powered, and the magnets inside the body engage when the ignition switch is turned on. The pinion gear (starter gear) is attached to a rod that is pushed out by this. The starter revolves as the equipment meets the flywheel.

The starter disengages, and the electromagnet ceases as the engine spins over. If the pinion gear remained in contact with the flywheel, the engine might destroy the starter by spinning it too fast.

Return springs on the rod help turn the starter motor off so it doesn’t turn more than necessary to start the engine because it takes a lot of electricity, which could drain the battery.

Step-by-step Guide To Replacing Your Starter

A few years ago, I faced this critical issue in my car. Of course, it is a common issue faced by car users around the world.

Thus, let us get into the step-by-step methods to diagnose and replace your car starter effectively.

A bad starter can also stand as a hurdle for your car to start. So, let us diagnose the starter then we shall move on to the next steps.

Diagnosing A Starter

First of all, disconnect the car battery from your car. To disconnect your car battery, utilize a suitable dimensioned socket wrench or hand to untie the nut, which protects the cable of the negative side of the battery.

One more thing is that you need not remove the nut entirely out of the battery terminal. Importantly, make sure that the cables do not get in touch with the battery while working. It is highly advisable to disconnect your battery while working with the electrical stuff in your car.

For a comfortable working position with the starter in your car, you can jack up your vehicle. The jack-up can provide you with the necessary safety regarding the damage you cause while working on your car starter. Ensure that your car has a good elevation from the ground level.

After setting all your necessary positions, search for the locator in your car. The starter is easy to locate. It runs near the wire that is running from the fuse or the battery box. It looks like a large cylinder devoted to a small cylinder.

If you couldn’t find your starter, the best way to find it is your user manual given while purchasing your car. The smaller cylinder combined with the start is called the solenoid.

Now you should disconnect the wire that runs from the solenoid. To disconnect the solenoid, you need to clip off your wires in some vehicles. In some cars, either you need to untie the screw, or you should loosen the bolts.

The maximum number of starters holds two retentive bolts, which grip the starter and lie near the transmission. To remove the bolts, use the appropriate removers, such as accurate-sized bolt removers. Make sure that you use the exact size while removing the bolts. While removing the bold, you may need to pull the starter with some force.

The procedure that I am instructing covers your safety as well as a good accuracy in results. Now we shall get into the next step. Our next step is to replace the starter from your car. Let’s join the step-by-step instructions to install the new starter in your vehicle.

Installing A New Starter

You should first follow while installing the new starter to compare the new starter with the old starter. This procedure ensures the size of the bolts with the previous starter and the new starter.

Comparing the previous starter and the new starter should be conducted because the starters are not identical; the new starter won’t fit in your car. The bolts, and the retainer bolts should exactly be the same. If not, then you have to get a new starter for your vehicle.

The next step you should take is to move the new starter to where we had the old starter. In some vehicles, you have to place it above the engine. In some vehicles, you have to put your new starter below the engine. So, it depends on the car you have.

To fix it, you need some support. Ask your friend to hold the new starter in the same position, while in the meantime, you can screw up the bolts for the starter for firm fixation. When you are about to fix it, you have to adjust the cables around or near the engine.

After adjusting the cables around the engine, place the starter where you should fix the new starter. As said before, you will need some person’s assistance. Confirm that you have a firm fixation over the bolts with regard to your new starter.

Due to the vibration of the engine, your bolts may get loose out. So, carefully tighten the bolts that act as vibrant proof. The next step you should take is to reconnect all the disconnected wires that we previously disconnected to remove the previous starter.

If you come across any queries to connect the starter solenoid, don’t worry. Just refer to your user manual. Once you have connected the solenoid starter with the proper wiring and everything needed, you have connected the battery wires back to their original position.

After connecting everything and finding that your vehicle didn’t start, I will give you another solution. Check the battery’s charge level. Sometimes, the car cannot start if it doesn’t have a sufficient charge. Thus, recharge your car battery and give it a try.

Though you charge your battery, you still can’t find your car engine to start. Then shook around the cables that you have connected all the wires correctly and plugged. Once checked, attempt to start your engine. If that doesn’t work, take a brush and clean all the dirt near your machine, and have a clean car engine.

Clean the battery area, then give it a try. If that idea doesn’t work, try checking the connections and battery. Hopefully, you can hear the sweet sound of the car engine starting.

What Are The Causes Of Starter Problems?

Bad Starter

A bad starter has several issues including:

  • Starter connections that are dirty or corroded
  • Fuse or relay failure
  • Parts of the starting system that are damaged or worn out
  • Loose electrical connections


So, once you’ve determined what problem you’re dealing with, you may begin to address it. Always start with the battery.

There isn’t a specified or advised replacement by the car manufacturer; problems with the starter are practically impossible to avoid. Contact a competent mechanic as soon as you observe freewheeling, grinding noises, or smoke, or your vehicle won’t start at all.
