Assumming your connections and ground are good, you have a bad coil. If you think of the two coils as one and you have a positive ground, then the + of one coil is grounded and the - of the other has voltage when the EI provides it. One coil cannot have "power" without the other having it. That leaves only the secondary of the two coils separate (able to fail).Ignition off, your meter set to ohms, lowest scale. Measure from the + of the coil with a ground wire to the + of the battery - must be 0 ohms. Then measure from the + of the coil with a ground wire to the head - must be 0 ohms. Repeat both with your meter on the highest ohms scale. For all four readings, ANY resistance is TOO MUCH. BTW, if using a digital meter with only one ohms scale, then use it and there are only two tests rather than four.
