You are on the itch to hit the road fast with your Cadillac Catera vehicle but it suddenly failed to run mainly because it failed to produce the needed sparks. When this happens, your Cadillac Catera ignition coil has a problem. The Cadillac ignition coil is a transformer-like component that takes the 12v DC powers and alters it to 40KV. The magnetic field causes a gush of high voltage current in the coil’s secondary windings. The high voltage current passes through the distributor going to the spark plugs where it jumps the plug gap and ignites the plugs. Just like the other parts, Cadillac ignition coil may tend to fail through time. If the internal wiring shorts or opens and when there is a crack around the high voltage terminal, it is a symptoms that your ignition coil is in trouble. Better replace it with a new one before waiting for further problems. For better replacement, make sure that you have a Cadillac Jacobs ignition coil.
