The simple answer is no, the coil case does not have to be grounded for the ignition to work properly.
Just so, do motorcycle coils have to be grounded?
The coil does not need an electrical ground, but it does need a thermal ground for heat dissipation, meaning that the "ground" could be compromised by paint etc. and still serve its purpose as a thermal point of dissipation.
Considering this, what are the symptoms of a bad ignition coil?
Usually a faulty ignition coil will produce a few symptoms that alert the driver of a potential issue.
- Engine misfires, rough idle, and loss of power. One of the most common symptoms associated with a faulty ignition coil is engine performance issues.
- Check Engine Light comes on.
- Car is not starting.
The ignition coil is the part of your engine that produces high voltage in order to power your cylinders. The distributor is what gets that high voltage from the coil to the right cylinder. The coil's ground side connects to breaker points, which are connected by a lever to a cam in the middle of the distributor.
