How do you check a coil?

A spark plug tester tool is the only safe way to test for spark. Measure the coil's primary and secondary resistance with an ohmmeter. The coil needs to be replaced if either of them is out of specifications. A digital 10 megaohm impedanceohmmeter can be used to bench test a coil.
