When you start the engine and release the key the circuit will, discontinue the power to the starting motor. If this stays on after the engine has started, the main contacts in the solenoid, have most likely failed. This will ultimately cause serious damage, to the whole starting system and the transmission flywheel.
If you try to start your engine and the engine doesn’t start instantly, you may have to try again. If it works the second time it is most likely, due to a problem with the relay.

The signal then continues to the starters solenoid, which activates the, high amperage side of the electrical system.
The relay is an all or nothing device, meaning that it either sends the full electrical current or nothing. In some occasions, a damaged relay can cause a, clicking sound when you turn the key.
For the engine to fire, one of the most important factors is turning of the flywheel. When the ignition key is turned a low amperage electrical signal, is sent to the anti-theft system and computer.
When the starter works properly, it sends power to the engine every time you engage it. But the starter may get damaged due to exposure to heat, debris, dirt and other issues, and its sporadic operation may get affected significantly. When you try to start your vehicle, it should activate immediately. If not, then there is most likely a problem with the starter. Sometimes, the problem may not be with the starter, but with the wire connection that might have become dirty due to exposure to the elements. [links]
When you turn on the ignition, you may hear the starter becoming active, but you can’t hear the sound of the motor crank. This might be a symptom of a mechanical issue with the starter. The problem is most probably lying in the gears connected with the flywheel. The gear must have stripped or it may have been dislodged against the car’s flywheel. Whatever the case, the engine will fail to turn over and you will have to get your starter replaced.
Most of the time, problems with starting your car are blamed on the battery. While this may be the likeliest culprit, the problem may also lie in your vehicle’s starter. How would you tell if the problem is related to the starter or any other electrical component of your vehicle? Firstly, you need to know that your starter has two parts. The primary motor starts your car’s engine by turning the crankshaft and the solenoid engages the drive gear. Although regular maintenance and servicing can keep your car in good condition, the starter may fail due to age, wear and tear. This oneHOWTO article will tell you about symptoms of bad failing starter, so that you can identify the problem and get it resolved accordingly.
The starter is usually located near the bottom of your vehicle. This means if there is an oil leak, it is likely to get drenched from other parts of the engine. A starter soaked in oil will have a shorter lifespan and will get damaged very soon. So, you should think about correcting the leakage immediately and replace the starter before any serious malfunction takes place. Oil leaks can be both an indicator and further cause of many engine problems. more
The circuit should close and discontinue supplying power to the motor as you release the key and start the engine. But if the starter still stays on after igniting the engine, the main contacts with the starter must have welded together in a closed position. If this happens, the starter gets stuck in the turned on position and causes damage to the circuit, starter relay and transmission flywheel. That’s why it is important to get the issue addressed immediately by a professional mechanic. [links]
If the starter has not yet failed completely, you may hear some clicking sounds, but it won’t turn over. This is usually caused due to the motor or the starter solenoid being burnt out. It might be experiencing some electrical issue as well. Although this kind of problem may arise due to a dead battery as well, you have to check the other symptoms so you can determine which one is at fault.

Whether the blades aren’t spinning or the fan is making tons of noise, most issues with an electric fan are caused by poor lubrication or blockages in the vents. To solve most problems with an electric fan, disassemble the fan, lubricate the central pin and bearings, and clean out the vent and motor case. Repairing an electric fan can be tough if the problem has anything to do with the motor itself, which may be dead if the fan makes no noise when it’s turned on and the blades don’t turn at all after cleaning and oiling the pin. Since electric fans tend to be inexpensive, it’s usually not worth it to bother trying to repair the motor on your own and you should consider simply buying a new fan. more

Over time, the starter motor will eventually run its course and wear out. The two components inside the starter that commonly fail are the solenoid (which sends an electrical signal to the starter motor to activate) or the starter motor itself. When this occurs, the starter will be rendered useless and needs to be replaced by a certified mechanic. Although many of the internal components inside the starter can be fixed, it's recommended by most automotive manufacturers to replace the starter, so as to avoid future breakdowns.
Problems with the starter are virtually impossible to avoid, as there really isn't a predetermined or recommended replacement by the automotive manufacturer. As soon as you notice freewheeling, grinding noises, smoke, or your vehicle not starting at all, contact a professional mechanic to further assist you in figuring out the problem.
Like any other mechanical device, when the starter fails or begins to wear out, it will display a few warning signs. Note the following 6 indicators of car starter problems:
In some instances that might be the case, however, sometimes the problem is the engine’s starter motor. When a starter motor is going bad, it may display a few warning signs. It’s also possible that you may have wiring issues or possibly a, bad ignition switch.
The first step in getting your starter motor problem properly diagnosed is to; rule out the battery. Remember that your battery will need to be fully charged; in order to operate the starter motor. more
