Dependable Vehicles Require Maintenance

Batteries, Alternators and Starters


The Electrical System: Your Car's Nerve Center

Repairing a carís electrical system means looking at three major components:

  • The battery
  • The starter
  • The alternator

The CAR Battery: The Source of All Power
Your carís battery is the primary source of electricity.  It provides the energy necessary to run conveniences such as clocks, radios and alarms.

Lovell's Automotive battery inspection looks at:

  • Overall car battery and case condition
  • Cable connections
  • Hold-down hardware
  • Electrolyte level (where applicable)

Then a Battery Load Test is performed to measure the batteryís power level as required by the battery.

The motor Starter: Getting A Move On
The starter motor converts electricity to mechanical energy to turn the engine over.  The starter requires a greater initial amount of current to flow from the battery to the starter motor to get the engine running.

Checking the starter means checking:

  • Cable connections
  • Mounting bolts and brackets

Then a Starter Electrical "Draw" Test is done, measuring the amount of electrical energy required to turn the engine over during cranking. 

The Alternator:  Keeping Your Car Running
Once the engine is running, the car's alternator takes over.  It powers the electrical system and restores energy to the battery.

Ensuring the Alternator is running means looking at:

  • An overall visual Inspection
  • The drive belt
  • Mounting brackets
  • Electrical connections

A Charging System Test checks alternator output (current) and voltage and ensures they are to manufacturer's specifications.

Working together, your carís battery, starter and alternator supply your car with electrical power.  The power level is stabilized with a voltage regulator and a fuse box that prevents small malfunctions from becoming major problems.
