Diagram of components of starting system arrangement

These components are as follows-
Battery: A group of cells is called a battery. It is an important auxiliary component used in the automobile sector.
Various devices requiring electricity are used in vehicles through it; Such as self-starter, meter, indicator and
gauge etc. are operated. Additionally, various activities while operating a motor vehicle; For example, batteries
are also used in lighting the lights of vehicles, blowing horns and operating wind screen wipers. The main parts of
a battery are box, plates, separator and terminals.

Battery Cable: A sheathed wire with one or more twisted wires is called cable. Battery cables are available in
different gauges and are used according to the nature of the work. At present, 02 and 04-gauge battery cables
are generally being used in vehicles. The lower the gauge of a wire, the greater the thickness of that wire; For
example, a 02-gauge cable will be thicker than a 04-gauge cable.

Neutral safety and ignition switch neutral safety and ignition switch

The device used to control the flow of electric current, i.e. to ‘start’ or ‘end’ it in an electrical circuit built for a
vehicle, is called a switch.
In the starting system, when the transmission is in any gear, neutral The safety switch opens the starter circuit.
This switch is generally connected to transmission leakage or directly to the transmission. In most cars this switch
is used to supply current to the backup lights. Additionally, the ignition switch is used to distribute electrical current
to the vehicle operator at desired conditions.
Starter Solenoid: Electro-magnetic device, starter solenoid or starter relay is used in the starting circuit to serve
two purposes, one is to complete the circuit between the battery and the starter and the other is to drive the starter
gimbal in conjunction with the engine ring, gear in the vehicle. Due to high current flow in vehicles, corrosion
occurs automatically in the starter, due to which the parts of the starter; Like brushes and winding need to be
changed.
