No spark / coil? 200 1986

Hmmm, I see everybody is jumping all over this one! Looking ar your readings they are not that far out of "spec" and, while the coil might be getting long in the tooth, it probably should fire. You can make a quick check by disconnecting the coil, attaching a wire from the negative side of the coil to negative on the battery. Attach another wire to the positive coil terminal. Secure the coil hi-tension lead close (maybe 1/8" or so) to a grounded metal object and touch the wire hooked to the positive of the coil to positive on the battery for a split second. A spark should be generated when the wire is removed from the battery.

How a coil works is when the points are closed (or wire attached to battery like in the test) a magnetic field builds in the primary coil windings. When the points open, the magnetic field collapses and generates a high voltage in the secondary coil windings.

The above example referred to "points" but an electronic ignition is similar, think of the hall sensor and ignition amp as the points...
