This is on a Bosch ignition, not Regina. I have no spark at the coil. I have swapped out the coil, and the power stage, with known good ones, and still no spark. I have 12 volts on the low tension side of the coil, but no spark. This means that the required pulse is not reaching the coil from the power stage, which is required for the coil to generate a high voltage pulse.
I have had trouble with my ignition switch, primarly sticking in start position. Is it possible that the ignition switch has further degraded,and that it is not sending a signal to the power stage, which then can't send a signal to the coil?
