Why not start the motor? Seven reasons

You are trying to start the motor but the starter is hard “not to notice” you. And what could he be offended?Revin Alex “driving”the ExpertKolodochkin Michael “at the wheel”Expert

Turned the ignition key, pressed the start button — how else let car engines? But no usual “W-W-W” not to hear: the machine won’t Wake up. What could happen?

Dead

The most common reason for the silence of the starter is a fully discharged battery.The most common reason for the silence of the starter is a fully discharged battery.

Ways to put the battery to zero quite banal: Unliquidated headlights to frequent and short city trips (especially in winter). There are cars with the original bad happens — say, heated rear window, stays on when the engine is off. The methods of recovery is also simple — charge, replace, etc.

Oxidized

Once upon a time, in such cases, one of the authors habitually climb under the hood of my dad’s Lada — almost certainly need to clean with fine sandpaper the battery terminals. Lada is long gone. But the oxidation has not been canceled, but because any modern machine, they can harm just as in ancient times. With respect to the starting system, with its vast currents even an extra 0.1 Ohm when a current of a hundred amperes is immediately “eats” all the tension in the end the starter will be silent.

Lost, burnt, disconnected

Following the “electric” the reason for the silence starter — disconnect the wire. If, for example, loose to the solenoid, you should know that the start will not.

One of two types of failure in electrical and electronics — no contact…One of the two types of failure in electrical and electronics — no contact…

Owners of older cars know that common disease of former times was the burning of the contacts 50 on the ignition switch: a solid current of the traction relay of a few tens of amps went directly through them, but because from time to time they failed.

Thickened

In an era of deficit many had to go to summer motor oil in the winter. In the evening he poured a glass of gasoline, and the engines before start-up fueled by all available means. But today is enough to fill a normal oil and forget about the problem.In an era of deficit many had to go to summer motor oil in the winter.

Summer oil during a hard frost is able to freeze so that the starter will be not under force to turn the crankshaft. The method of treatment is obvious: change the oil on the right.

Locked

The starter interlock security device — the usual case. Usually fail under non-standard device, and in some cases, blame the owner. Just forgot to disable it.

The starter itself is faulty

Today rarely imagine the kind of starter on the inside. Maybe so be it — the extra knowledge.Today rarely imagine the kind of starter on the inside. Maybe so be it — the extra knowledge.

Rarely, but it happens sometimes: sometimes starters die. Anchor, brush, solenoid switch and contact screws — it doesn’t matter.

Stuck

Even jamming the generator can prevent the starter motor to crank.Even jamming the generator can prevent the starter motor to crank.

But it is very bad situation. Not so bad if you stuck a support unit including a generator, pump, air conditioning compressor or power steering pump. But if wedge grabbed Sam engine, it’s a sentence — to-overhaul- with all the ensuing consequences.
