A starter motor in a car is a cranking contrivance used to crank the internal combustion engine to bring the vehicle into the state of operation. It allows the engine to start by spinning over the turning crankshaft. The failure of a starter motor can be annoying. Sometimes, it burns up due to manufacturing defects, and sometimes, the cause can be a solenoidal issue or a user error. Incorrect starter fluid also puts a lot of stress on the starter. Some problems are virtually impossible to avoid. To avoid hefty repair bill on repair, you have to keep up with the recommend replacement interval and keep an eye on the vehicle’s abnormality related to the performance.

1. WHAT CAUSES A
STARTER MOTOR TO
BURN OUT?

2. An internal combustion engine is a
feedback system which depends on the
inertia of the first cycle to start the next
cycle.

3. The primary job of a starter motor is to
generate the crank required to start an
internal combustion engine.

4. By doing so, it plays an important role in
the performance of a car engine. However, a
defective or abnormal starter motor fails to
start a car engine.

5. So, signs of a starter motor failure should
not be neglected and root causes of the
starter motor failure should be repaired
immediately.

6. CAUSES OF A
STARTER MOTOR
BURN OUT

7. Primary functions of an ignition switch is to
establish an electrical pathway between the
battery and the starter motor.
FAULTY IGNITION
SWITCH

8. Besides, it also helps to activate the
electrical system and different components
of the ignition system of a car.

9. Starter motor disengages once the engine
gets operational.

10. However, if the ignition switch gets stuck,
then the starter will not disengage in time
which could lead to the starter motor
burning out.

11. Starter solenoid is directly attached to the
starter motor and its primary function is to
connect the starter pinion with the flywheel
of the engine.

STARTER
SOLENOID

12. It also helps to disconnect the pinion from
the flywheel of the engine.

13. If it fails to disengage the pinion once the
engine has been started, then it could
damage the starter motor of the car.

14. Deposition of dirt particles, oxides of metals
or other kinds of contaminants inside the
starter motor might trigger major problems
in this component.
CONTAMINATION
AND USER ERRORS

15. Besides, if a person turns the ignition key
longer than required, then it could lead to
starter motor burn out.

16. Moreover, faults in the wiring system which
connects the ignition switch with the starter
motor might also cause starter motor
failure.

17. FINALLY

18. A starter motor is an important part of the
ignition system of a car.

19. It engages with the engine to start the
combustion cycle and disengages once the
engine begins to operate.

20. However, a burn out starter could not do its
job as a result of which the engine fails to
start.

21. So, root causes of starter motor burn out
needs to be detected and repaired in time.
