Seeking the Elusive Electrical Problem. Many times electrical problems are the most elusive, because they can occur intermittently. For example, the car engine may not work properly, but only after the engine warms up. Or the ignition works randomly. Perhaps the engine cuts out without notice while cruising down the highway. Then again, your car might have a faulty alternator or a defective wire.
The charging system will normally consist of two major components: An Alternator which actually supplies the necessary electrical current in order to charge the battery, and a Voltage Regulator. The latter insures that the system does not overcharge the battery, and that the correct system voltage is maintained. Most vehicles produced within the last 20-30 years use a voltage regulator which is an integral part of the alternator itself. This article assumes that your vehicle uses this type of alternator.
Modern cars come with complex electrical systems meaning that electrical diagnostics tools are needed in the repair and maintenance. That being said, the following are some of the most common auto diagnostic tools you will find in most auto electric repair shops. Digital motor checker - This is a vehicle diagnostic tool used in the maintenance of inbuilt electrical systems without any dismantling having to be done. This device helps in detecting problems that may result in tripping and therefore compromised electrics.
Starter: starting the car was a sweat-breaking business before the starter. A procedure by it's own, where you had to be fairly skilled. Cranking the car was done with a cranking rod. The driver would put it into place, use all the strength available, crank the engine and if he's lucky the engine would start after a few turns. If not, he was in for another lesson in body-building. Aside that, when the engine started the driver had to let loose of the rod in time or else he would get a knock in the face. Every time you put the key into the ignition, remember this and enjoy it as a privilege.
