 Getting to know semi truck electrical system
Guess which electrical part is the main power source for your semi truck when it’s running?
A. Starter
B. Battery
C. Alternator
D. Engine
Your are right! It is Alternator. The alternator AKA generator is a crucial part of the electrical system because it supplies the running vehicle with power. Without alternator and other electrical components like starter and battery, a vehicle wouldn’t turn on, and many parts in the vehicle wouldn’t work properly. Let's take a closer look at a truck’s electrical system and how it operates to prevent costly breakdowns.

Main components of the electrical system are starter, battery and alternator. They are responsible for igniting the engine, keeping it running and powering other electrical components in the vehicle. Components like wipers, A/C, truck and trailer lights, windows and door locks, radio and more. Check out the below information to understand each one of those components.
Starter also know as cranking motor converts electrical power into mechanical power through the starter relay and starter solenoid and provides electricity to the pinion gear and flywheel.

 Indicators of a starter that is coming to its end.
Your starter may be experience problems if one of the following is happening:
  • It doesn’t turn on right away when you insert the key into the ignition
  • Clicking or whining sound when the key is turned
  • Smoke comes out of the starter​
 Battery
You won't be able to start the truck if you don't have a battery. That's why battery is considered the main electrical part in the truck. Battery also stores energy when the truck is off, and powers items in your truck like microwaves, radios, tv when truck is not running. Very handy function for OTR drivers.
Indicators of a faulty battery
  • The battery light is on
  • Strong sulfur smell
  • Leaking battery chemicals
  • Engine cranks very slow
 Alternator
Alternator is the main source of electricity for vehicle when it’s running. Alternator converts mechanical energy from starter into electrical energy to charge the battery and power electrical accessories at the same time. It is the alternator that keeps the vehicle from shutting off when truck is on idle or running.
Alternator needs your attention when:
  • There is odd grinding noise
  • Your battery is dead
  • Power looses power
  • Lights are deem
Best way to maintain truck electrical system.
​
With the vehicle getting old, mileage adding up and daily driving conditions affects your alternator and keep it from starting or functioning as well. By implementing preventative maintenance, potential alternator problems can be found and repaired. These are some tips: 
  • Keep your battery cables clean by doing PTI
  • Keep an eye on loose plugs and cables
  • Keep all lights off when the truck is not running
