This system is my own design and there are couple of things I don,t like about it hence the new version.
My main gripe is the closeness if the transistor legs , the darlington transistor in the next one I built has it,s legs twice as far apart, They are about 5mm apart as
oposed 2.5 mm on the IGB transistor
as you can see in the picture below.
The schematic showing the 10uf and 330k resistor timing section that turns off the coil if the engine stops
with the sensor over the slot.
