Ignition Coil Driver Relay - How To Wire It - High Voltage Sparks

This is my Ignition coil driver using a 12V 40A car relay and including a 500V 22uf capacitor. I also include details of how I wired the circuit. I realise there are many videos of relay driven coils out there, but in my opinion the details of how to wire the relay circuit is sketchy. I hope my description will be more helpful. Any comments on improvement and how to get longer sparks would be appreciated. I originally powered this setup using a Mains 12V 1.5A adapter, however I received a minor shock whilst trying to switch the adapter off at the wall socket, can anyone tell me why this happened? The relay I used has terminals numbered 85 86 87 87a and 30. It does not say which terminals are the NC terminals which most people use. Hope you find this video useful as not only do I show sparks, but also include details of how its wired in a diagram. The relay is wired to produce pulsed DC whch is input to the ignition coil. These pulses are produced by the relay making and breaking its connection many times per second. On the breaking of the connection the magnetic field inside the ignition coil collapses suddenly and induces massive voltage in the coils secondary windings.
