GMC Terrain Ignition Coil

The Ignition Coil in GMC Terrain vehicles is correct in transferring the low voltage from the battery into high voltage required to cause combustion of the fuel in the combustion chambers. This component is the tying point between the primary and secondary circuits in the ignition system; the primary winding comes from the battery and triggering tool, while the secondary winding produces the high voltage necessary for spark plugs. Depending on the vehicle model, GMC Terrain ignition coils can be of distributor ignition coil type, coil-on-plug ignition coil type, or wasted spark ignition coil type; every of them will employ its specific method for providing electrical voltage to the spark plugs. The primary duty of the ignition coil is to provide the spark plugs with the required voltage to ignite the fuel, any issue with the ignition coil means that the engine will be starved of spark resulting in; efficiency loss, slow acceleration and poor fuel efficiency thus it is crucial for this part to be checked as frequently as possible.
