Distributor Tach Output signal
Wow, two posts in a row...
Anyway, does anyone know what the signal looks like coming out of the tach output on the distributor? Square wave? 1 pulse per spark? Looks like it is 12v that drops to ground once per spark, but I'm not real sure. Don't have a osciliscope anymore. Anyone have this info?
