To test a coil pack, use an ohm meter to check for continuity, ensuring that the ohm values are accurate. Buy a Chilton?s or Haynes manual to determine the appropriate mega ohms reading on the coil pack, or search for th... More »

Diagnose a bad coil pack by using an ohmmeter to compare the vehicle's readings to standard values for the vehicle. Use a scan tool to determine which cylinders are misfiring as a result of the defective ignition coil. W... More »

A coil pack, also referred to as an ignition coil, is a component in the car's engine that changes current generated by the battery into a high-voltage current used by spark plugs. A typical coil pack transforms the 12 v... More »

An Ohm's Law calculator is used to substitute values into an equation that compares voltage to resistance to determine electrical current. On a DC circuit, it is a straightforward ratio, but even with AC, it can be used ... More »
