The Ignition Coil in GMC Acadia vehicles basically helps to convert the low voltage current obtained from the battery to high voltage capable of igniting the Squib mixture in the cylinders. It is the link between the primary and secondary circuits; primary circulation encompassing battery, ignition switch and triggering device while the secondary circulation includes the high tension lead and spark plug wires. Auto GMC Acadia Ignition Coils basically consist of two turns of insulated copper wire, known as primary and secondary coils, all encased in a plastic, epoxy or polymer housing and having an iron core. Based on the used type of ignition system, the coil can be connected to the distributor cap and the rotor or it can be connected directly to every plug. Damage or malfunction of the Ignition Coil can cause the vehicle not to start, or a cylinder to die; it produces rough idle, poor performance, and poor fuel economy. It is important to carry out a daily check on the coil's resistance and voltage pattern for good engine health.
