Frequently Asked Questions

These parts are the battery, starter and alternator. The battery provides needed electricity to the starter, which starts the engine. The alternator provides the battery with enough energy to continue powering your car while running.

Some of the most common signs of auto electrical problems include:


  • New car batteries that get easily drained
  • Engine starting difficulties like not cranking properly and “clicking”
  • Malfunctioning lights
  • Blown fuses

Computer systems or ECUs are extremely sophisticated and complex for DIY approaches, which can lead to even bigger engine problems. The best thing you can do is to bring your car to a shop with a qualified auto electrician.
