Shuttering

[Ed_Strong]

I know Auto Zone auto parts checks your alternator, starter motor and such for problems, but does anyone know if they also check coils?

Don't know. Call around. I also have provided the test procedure in more than one thread here in the windy forum recently.

The resistance check of the coil is VERY good.
However, it will not catch arcing due to a crack in the epoxy.....a common failure.

Sometimes you can tell your coil is cracked if you find leaked oil around or on it. The coils inside are packed in oil. If the arcing is occuring on the exterior, you may be able to see a discolored line like mark on its outside.
