What are some good sites to use for automotive troubleshooting?

The Consumer Information website from the Federal Trade Commissions offers information on troubleshooting, repairing and preventing automotive problems. Common troubleshooting areas include the alternator, battery, starter, muffler and tune-up, according to the FTC.

Loose wiring can make an alternator appear faulty, and loose battery terminals can make the battery seem dead or defective. What appears to be a defective starter actually may be a dead battery or poor connection, and a loud rumbling noise under the vehicle indicates a need for a new muffler or exhaust pipe.

Another trustworthy source is the National Institute for Automotive Service Excellence. The ASE is an independent non-profit organization working to improve the quality of vehicle repair and service by testing and certifying automotive professionals.
