An ignition coil takes voltage from the battery and multiplies it to create a spark at the spark plugs, which in turn ignites the engine. Cars have been using some form of the coil ignition system ...

The other system is the CD, or capacitive discharge, ignition in which a capacitor stores electrical energy and releases it to the coil. In these systems, more or less voltage does not affect the ...

A diagnosis of any electrical system, whether it is 12 or 24 volts, must include two key elements. First, you must test the complete circuit. Second, you must understand how that circuit works. One of ...
