What are the basic principles of ignition coil technology?
In general, ignition coil technology can be split into two fundamental operating principles: ‘single spark technology’ and ‘dual spark technology’. With single spark technology, there is an individual coil for each spark plug supplied.
What are the terminals on an ignition coil?
The side terminals of the coil are marked positive (+) and negative (–) and these are where you can measure the resistance of the primary windings. Set the multimeter to the 200-ohm setting and attach the meter’s leads corresponding to the terminal markings, red being positive and black being negative.
What kind of ignition coil does a corvette have?
The coils on early Corvettes are black cylindrical devices; starting in 1975 the coil per se as a discrete cylindrical device was abandoned when GM made the switch to HEI breakerless ignition systems.
What kind of transformer is an ignition coil?
An ignition coil is a type of pulse transformer that multiplies the low voltage received from the battery or alternator to many thousands of volts when the breaker points open and close.
