The main function of car starting circuit is using the small current from the car battery to control the large current of the car starting circuit, thus to start the starter motor and power the engine. There are three main components in the switch starting circuit: ignition switchstarter solenoidstarter relay.

Usually, the ignition switch connects with a key or a button, and inside of it has the regular wire connects to the car battery. When the ignition switch is turned or pressed the button to start position, there will be a small current flow through the starter solenoid coil, allow sufficient current flow to the starter. Expect to take part in starting control circuit, the ignition switch also has other functions, such as lock the steering wheel, connected to car electrical system, and connected to the vehicle computer fault diagnosis.

The starter solenoid is the main part of the control starter circuit, including the with relay type and non-relay type. The solenoid switch is composed of a solenoid, which is an electromagnetic device that produces the attraction or retention of the moving core. Most of the starter solenoid is fixed directly to the top of the starter. The starter relay is another switch that is used to control the starting circuit. In the start control circuit, the relay is connected in series with the battery to shorten the transmission of the large current cable length.

In mini cars equipped with small power starter, the ignition switch start position is used to control the starter solenoid switch directly, as shown in the picture below. When large power starter is equipped, in order to reduce intensity of the current that passes through the ignition switch and avoid ablation of the switch, the start relay is often used to control the heavy current of the starter solenoid switch, and the ignition switch Start position is used to control the low current of the relay coil.

The single relay controlled starter solenoid wiring diagram is as shown in the following picture. The automatic transmission equips with neutral starting switch, which is in series connection to the bonding terminal of the start relay coil. Neutral starting switch is on only in the case that the automatic transmission gear lever is in parking position P and neutral position N.

In other gears, the switch is in an off state, so as to avoid damages to machine parts caused by misoperation. To ensure that the starter can stall automatically and the starter circuit not connected after the engine starts, some cars adopt the compound relay circuit with safety driving protection.

Before the engine starts, the alternator does not generate electricity, the voltage of the neutral tap N binding post is zero, no current passes through the charge light relay, Starter relay coil and charging indicator relay contacts are connected to ground.

After the engine starts, the neutral tap N terminal post of the car alternator outputs proper voltage, which acts on the charge light relay coil and cut-off the current of the starter relay. At this point, even if the ignition switch key not loosened timely, or the key is incorrectly rotated to the ST position again, the starter will not operate.

Ignition Switch Usually, the ignition switch connects with a key or a button, and inside of it has the regular wire connects to the car battery. Starter Solenoid The starter solenoid is the main part of the control starter circuit, including the with relay type and non-relay type. Starter Relay The starter relay is another switch that is used to control the starting circuit.

Thank You For Your Inquiry.Recently I asked our engineers a few questions about the starter solenoid:.

So yes, we nearly know nothing about the starter solenoid that most people want to know. But not anymore! We made this guide for you, to help you know more about the starter solenoid.

From what is it, to how to wire it, from how to replace it to how to repair it by yourself. Trust me, this is the best starter solenoid guide online.

A starter solenoid is a combination of solenoid and switches Full name: Starter Solenoid Switch. As we all know, the starting of the engine requires external support, and the car starter is playing this role. In general, the starter uses three components to achieve the entire starting process. Drive the starter pinion engaging in the flywheel ring gear. Function 1 When turn on the ignition switch and the starter circuit is turned on, the electric current flows to Starter Solenoid and create the electromagnetic force.

The electromagnetic force of the solenoid switch sucks the movable iron core in the Starter Solenoid to contact the two terminals, one of which connect to the positive pole of the battery and the other terminal to the starter. Function 2 The electric current divides into two streams flowing through the Starter Solenoid:.

A stream flow through the sucking coil, generating a magnetic force to sucks the movable iron core and move the fork backward so that the starter pinion can engage the engine flywheel. The another stream flows through the holding coil, creating a magnetic force to keep the core in the post-pulling position until the starting complete. In a car starter motor with Starter Solenoid, the Starter Solenoid is usually mounted directly on the to of starter motor. So where is the starter motor, where is the starter solenoid.

The whole process of starter solenoid switch can be divided into 3 stages: Sucking, holding, return.

When the ignition switch turns to the START positionthe battery current flows to the sucking coil and hold coil. The current then flows from the sucking coil to the armature coil thus make the coil rotated at a low speed. Through the sucking operation, the starter drive pinion will be pushed out and engaged with the ring gear. Also, the contact plate closes the main contact point.

When the main contact point of the plate close, no current flows through the sucking coil. So, the magnetic field coil and the armature coil can get the electric current directly from the battery.To wire a volt starter solenoid, first disconnect the black negative cable from the vehicle's battery, and then connect the red battery cable to the large bolt on the solenoid.

If it is a remote-mounted solenoid, you must connect a control wire between the control circuit terminal on the solenoid and the car's ignition bypass terminal. On-starter solenoids may be located on an assembly that is only accessible from under the vehicle, so lift the vehicle using a jack if necessary before beginning the process of wiring the solenoid.

When connecting an on-starter solenoid, be sure to rest the solenoid somewhere convenient while wiring it, since it is heavy and awkwardly shaped, making delicate connections difficult to wire if holding the device in one hand.

After connecting the red battery cable to the solenoid bolt, connect the bypass ignition terminal wire to a small bolt under the first one. You are then ready to lower the vehicle and connect the black negative cable back to the battery. For remote-mounted solenoids, the extra cable that must be connected is typically marked with the letter "S. Home World View. How Are Homemade Doorbells Made?I have had starter issues with just about everything I have owned.

No engine crank. You know the battery is good, you have the clutch pulled if it has onethe ATV is in neutral, and the light is on but still… nothing. The first thing you should do in this situation is to check the battery and connections. If you haven't read our post on multimeters yet, now's a good time to check it out. Once you have verified that the battery is NOT your problem, the next thing you should look at is the starter solenoid.

An ATV starter solenoid can normally be found on the frame. It is usually located on the outside of the plastic right next to or under the battery and near the wiring harness.

A starter solenoid is a switch that controls a high amp load with a low amp. Starter solenoids come in all different shapes and sizes, but normally they have a round or square body with two larger and two smaller wires.

The larger wires are for the high amp load and the smaller wires are for the low amp switch. If yours only has one smaller wire, the ground is coming from the frame where it is mounted. It may be sitting in a plastic or rubber cover, but it's not uncommon for it to be on the outside. Of the two larger wires, one of them will be coming from the battery red and the other will go to the starter black. You should be able to get a voltage reading from the red wire coming from the battery.

Do this by using the voltage setting on your multimeter, with the red lead on the post and the black lead on a frame ground or negative battery terminal. If you do not have voltage at the post on the solenoid that connects to the battery, check your connection at the battery and then trace the cable from the battery to the solenoid checking for any breaks or a loose connection.

Of the two smaller wires, one is a negative, or a ground, and the other is positive. I have found that the easiest way for me to test these is to unplug the connector and put both test leads into the ATV wiring harness side connector; the reading here should also be zero.

Now turn the key and get the bike ready to start do not actually start the bike, just take the usual steps you would before starting; i.

This step can get kind of tricky if you've only got one set of hands. I definitely recommend using test leads with alligator clips on the ends. You can pick up the clips for around 50 cents a piece and make your own or buy a pre-made set for a couple of bucks.

This battery in this photo is our test battery, so we expect the voltage to be a little low. We use this guy whenever we've bought a used ATV without a battery or for demonstration purposes.

Along with our multimeter, he's made appearances herehereand here. As long as you have a reading that is close to 12V, we'll move on. If not, you may want to run this test a few more times to make sure you have done all of the normal stuff you would do when you start your ATV like making sure it is in neutral, all of your wires are connected, etc.

I know it is redundant but you would not believe the amount of times I have been called out to a HMMWV that would be a Hummer in civilian speak that would not start, only to find it was left in gear.

If you still are unable to get a voltage reading, more than likely there is an issue with a safety switch or a kill switch. Due to the vast differences between ATV models, you will want to refer to the service manual for your specific model of ATV. If you are stuck on this step, feel free to contact us and I will see what I can dig up for you. If you've gotten a voltage reading close to 12V, you can confirm that thepush button is working and giving the solenoid the signal to close.

The last thing to check now is the starter. To test the connection between the solenoid and the starter, plug the connector back into the wiring harness and test for voltage on the starter side big terminal while pushing the start button. If you've gotten a voltage reading close to 12V, you can confirm that the push button is working and giving the solenoid the signal to close. If you do not have voltage reading, then your solenoid is bad and will need to be replaced.Wondering "Where-'n-'Ell" to get great parts for your outboard?

It consists of a powerful DC Direct Current electric motor and the starter solenoid that is attached to the motor see the picture.

Starter motor. Click for a larger photo. In most cars, a starter motor is bolted to the engine or transmission, check these photos: photo 1, photo 2. See how the starter motor works inside on the next page. The starter motor is powered by the car volt battery. To turn over the engine, the starter motor requires a very high electric current, which means the battery has to have sufficient power.

If the battery is discharged, the lights in a car might come on, but it won't be enough power current to turn over the starter motor.

What are the symptoms of a bad starter motor: When starting a car with a fully charged battery, there is a single click or nothing happens at all. The starter motor doesn't run, even though there is a Volt power at the starter control terminal. Another symptom is when the starter motor runs, but fails to turn over the engine.

Often, this might cause a loud screeching noise when starting the car. Of course, this could also be caused by damaged teeth on the ring gear of the flex plate or flywheel. Starter solenoid Starter solenoid. A typical starter solenoid has one small connector for the starter control wire the white connector in the photo and two large terminals: one for the positive battery cable and the other for the thick wire that powers the starter motor itself see the diagram below.

The starter solenoid works as a powerful electric relay. When activated, through the control terminal, the solenoid closes the hi-current electric circuit and sends the battery power to the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh with the ring gear of the engine flexplate or flywheel. Advertisement - Continue reading below Battery cables Starting system simplified diagram. As we mentioned, the starter motor requires a very high electric current to turn over the engine, that's why it's connected to the battery with thick large gauge cables see the diagram.

The negative ground cable connects the negative " - " battery terminal to the engine cylinder block, or transmission, close to the starter. Often, a poor connection at one of the battery cables can cause the starter motor not to run. How the starting system works: When you turn the ignition key to the START position, or press the START button, if the transmission is in Park or Neutral, the battery voltage goes through the starter control circuit and activates the starter solenoid.

The starter solenoid powers the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh it with the engine flywheel flexplate in an automatic transmission. The flywheel is attached to the engine crankshaft.The U. Chamber of Commerce shared its insight on the Paycheck Protection Program.

I tested them first and they all tested good but I jumped them anyway. Key switch still wouldn't turn engine over. Still nothing. Someone told me to run a wire from the yellow wire going into the key switch to the hot terminal on the solenoid. I did and now key switch will turn engine over and it will start but when I let go of the key it dies. As long as key is turned to the crank position it will run, of course starter is engaged while it's running so that no good.

Anyone know why it will run when held in cranking position? I checked voltage on wire that I ran to solenoid from yellow wire at key switch and it doesn't show any voltage no matter what position the key is in. Obviously that wire is bypassing something to make the key switch work but I don't know what. Any ideas? Wes ParkerMar 21, Messages: 2, Pull up the parts manual and look at the wiring diagrams, the yellow wire goes to the start relay. Look at the wiring diagrams and start looking at the start relay.
