Auto Electrical Faults That Trigger Engine Problems

The majority of engine problems such as hard starting, stalling, rough idle and engine warning lights are due to electrical malfunctions and not mechanical failure. Problems such as a declining battery, a malfunctioning alternator or a faulty starter can affect the sensor signals leading to erratic engine operation. The improper installation of accessories such as LED lighting bars and brake controllers creates further intermittent problems. Professional auto electrical repair focuses on the root of the problem using diagnostic testing before costly mechanical parts are needlessly replaced.
