Take the ground wire off the coil an see if it sparks. This will eliminate all the other electronics. If it sparks with the ground wire off it is in the chassis electrical system. If it does not it is in the ignition electrical systmem.

Remember that these vintage BMWs are build like they are two complete systems. One is chassis and one is ignition/charging. The only things they share is the mag ground wire and a couple wires for the charging system.

Try that first....
