Description

Most drivers improvise if the starter is faulty or battery power is low. The improvising is done by pushing the vehicle back or fro just to begin the combustion process. Though this is not highly advisable, but in a situation where the battery needs to be charged by the vehicle’s alternator. 

Battery cables

As we mentioned, the starter motor requires 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. The positive cable connects the positive "+" battery terminal to the starter solenoid. Often, a poor connection at one of the battery cables can cause the starter motor not to work.

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 starter motor spins, turning over the engine crankshaft allowing the engine to start. In cars with a push button start, the system disengages the starter as soon as the engine starts running.

The working of a starter is quite easy and interesting, but most drivers really don’t know the secret behind motor cranking. When the ignition key or bottom is press, the transmission should be in park or neutral state. The battery voltage goes to through the starter control circuit to activates the solenoid.
