What is an Alternator?

An automotive charging system is made up of three major components: the battery, the voltage regulator and an alternator. The alternator works with the battery to generate power for the electrical components of a vehicle, like the interior and exterior lights, and the instrument panel. An alternator gets its name from the term alternating current (AC).

What is a Starter Motor?

To make an engine start it must be turned at some speed, so that it sucks fuel and air into the cylinders, and compresses it.

The powerful electric starter motor does the turning. Its shaft carries a small pinion (gearwheel) which engages with a large gear ring around the rim of the engine flywheel.

  • Is Normally composed of heavy copper wire wound around an armature.
  • Is placed inside of a heavy steel or aluminum case.
  • Has electrical brushes that contact the armature and pass the electrical charge to the heavy wire

Car Batteries

Automotive batteries have a finite life span. Undercharging, overcharging and heat all team up to degrade your battery. Poor electrical connections make it more difficult for even a good battery to do its job.

If the battery shows less voltage or won’t take a charge, it’s time to get out the hydrometer. This device checks the proportions of sulfuric acid and water in the electrolyte, which is a precise indication of the level of charge. Pull up the battery fill caps–if you can. Add distilled water to any cells in which the level of electrolyte isn’t touching the bottom of the fill port. Use only distilled water. The minerals in tap water will eventually reduce a battery’s capacity.

If the level of electrolyte is very low, suspect a charging system that’s generating too high a voltage. The maximum voltage you should see across the battery terminals with a fully charged battery and an engine running well above idle is about 14.6 volts.
