I AM WIRING UP A 1953 FLH. I AM USING A NEW (GREEN) ANDREWS COIL BUT I AM NOT SURE WHICH END IS POSITIVE. THE COIL WILL ONLY MOUNT ONE WAY. THE COIL IS STAMPED "ANDREWS". IS THE 'A' END (top )POSITIVE OR THE 'S'END(bottom) POSITIVE? I HAVE A MALLORY IGNITION WITH THE STANDARD THREE WIRES,RED, GREEN AND BROWN. CURRENTLY I AM RUNNING GREEN TO THE BOTTOM OF THE COIL,RED TO THE TOP,ALONG WITH WIRE FROM IGN.SWITCH. DOES THIS SOUND CORRECT? THIS SOUNDS LIKE A DUMB QUESTION BUT HELP... I AM WIRING FROM SCRATCH WITH NO DIAGRAM. THANKS
