Choose Your Car Electrical System Help Topic Below
So, The Car Electrical System is way more than; just the stuff you see under the hood. Consequently, Apart from the main charging; starting and ignition circuits; there are many other circuits.
As a result, Many of these circuits power:
- Electric motors
- The sensors and gauges of electrical instruments
- Heating elements
- Magnetically operated locks
- The radio
So, How Do We Measure This Information:
Modern cars have a 12 volt battery. A batteries capacity is measured in amp/hours. So, A 56 amp/hour battery should be able to; deliver a current of 1 amp for 56 hours. Finally, If the battery voltage drops; less current flows; and eventually there is not enough; to make the components work.
Short Circuits And Fuses
So, The current in a wire may become dangerously high; and melt the wire or cause a fire. So, To guard against this; ancillary circuits have fuses. The sudden surge of high current in a short circuit makes the fuse wire melt; or ‘blow’, breaking the circuit. When this happens; see if there is a short circuit or a disconnection. Then install a new fuse; of the correct amperage rating. There are many fuses; each protecting a small group of components. Consequently, So that one blown fuse does not shut down the whole system.
So, The starter motor has its own heavy cable; direct from the battery. Also, The ignition circuit furnishes; the high-tension impulses to the spark plugs. And, Finally, The charging system includes the alternator; which recharges the battery.
