Frequently Asked Questions:

(1)What causes a starter to go bad?
CAUSES OF FAULTY STARTERS: CAUSE OF FAILURE
Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Single-pinion gear, starter pinion or freewheel damaged.

(2)What can kill a starter?
As said, the starter will be damaged if you hold it in the start position for a long time and it overheats. As said, the starter will be damaged if you hold it in the start position for a long time and it overheats. Particularly if the voltage is low enough that the starter motor is not turning.

(3)How long will a bad starter last?
On average, a starter motor lasts for 100,000-150,000 miles. In many cars, the starter motor lasts for the lifetime of the vehicle; however in some cars, it can fail prematurely.

(4)Will hitting a starter make it work?
Tapping on the starter usually doesn't make the starter work if the solenoid is bad (think Nippondenso). OTOH, a starter with a bad armature segment responds well to tapping or banging with a hammer. ... If the starter is bad, then sometimes banging on it can persuade it to work.

(5)Will a bad starter drain your battery?
A 'bad' starter wont drain the battery while it is not being used to start the car, if that is what you mean. If the starter has a damaged commutator, it will not run at full power and so could mean that you have to turn the engine over longer to get the engine to start which will use more energy from the battery.

(6)Does cold weather affect starter?
Cold weather usually thickens the engine oil. Therefore, the starters require more power to start the engine. This brings in more load onto the battery affecting it severely. During winters, the battery produces less electrons as compared to warmer days.

(7).I have to change the starter fairly often in my car. What could be causing this?
A leak of some sort could be fouling the starter if fluid is dripping on it. If that's the case,

replacing the starter doesn't fix the leak so it's only a matter of time before the new starter fails.
