Ignition System questions with
complete solutions
An Ignition switch - ANS ✔✔An Ignition (or starter) switch is a switch in the control system of an
internal combustion engine motor vehicle that activates the main electrical systems for the
vehicle.
What happens when the ignition key is turned - ANS ✔✔When the ignition key is turned all the
way to the "start" position, it allows electricity to flow to the starter solenoid (relay) which then
connects the battery to the starter motor.
Battery - ANS ✔✔Automotive SLI batteries are usually lead-acid type, and are made of six
galvanic cells in series to provide a 12-volt system.
Battery cables - ANS ✔✔Battery & starter cables.
Red or black.
Heavy duty cables for main connections between battery and starter.
Copper conductors, PVC insulation.
A starter solenoid - ANS ✔✔A starter solenoid is the part of an automobile which relays a large
electric current to the starter motor, which in turn sets the engine in motion. In many vehicles
the solenoid also engages the starter pinion with the ring gear of the engine.
Starter motor with solenoid - ANS ✔✔
What's in a starter motor? - ANS ✔✔The pinion is moved by the solenoid,there is an initial
period during which the motor turns slowly to allow engagement,which makes the whole
operation gentler and causes less wear on the teeth.
