my s1 just stopped whilst driving along and after a quick check it seems to not be getting a spark from the coil

ive tried 2 other coils with no joy so i got out the test light

connected the test light between the negative (green) wire unplugged off the coil and the battery positive terminal and have a constant light, turn the car over and it stays constant and dosen't flash/pulse



i connected the test light between the postive wire unplugged off the coil and the battery negative terminal and the light is constant

also the coil gets quite hot with the ignition left on

any ideas?
