Auto Electrical Repair: How to Diagnose Problems!

Accurate auto electrical diagnosis is one of the most difficult challenges when working on today's automobiles. Considering the large number of systems in a vehicle that uses electricity in order to operate, it is critical to be able to quickly diagnose problems to perform the correct auto electrical repair. Whether you are having problems with an engine control issue, an automatic ride height system, or a power window issue, or starters and alternators, the electrical systems all utilize the same principles.

Because auto electrical problems are so difficult to diagnose, you can help your mechanic determine where to look first for problems. The appropriate auto electrical repair can then be taken care of to get you back on the road again.

• Verify the problem --

This is more challenging than it sounds. Sometimes duplicating the auto electrical problem can be the most challenging aspect of the diagnosis, especially if it occurs only intermittently. Collecting as much information about exactly when the problem occurs will help your technician, to duplicate and confirm a problem.

Useful information for the auto electrical repair technician includes:

  • How often does the problem occur?
  • How long after the vehicle is started does the problem occur?
  • Does the problem occur only over bumps or when turning corners?
  • Does weather and temperature have any effect on the problem?
  • Does the car have to be idling, driving, in reverse, moving forward, be in gear, etc.?

Try to be as exact as possible in collecting information.

• Determine related symptoms --

This serves to help you isolate which circuit, or which part of the circuit, has the problem that needs to be repaired. By identifying related symptoms you can often eliminate unnecessary diagnostic procedures. Knowing an approximate area where the problem is gives your technician a definite direction in diagnostic testing.
