I'm working on an old 1975 mustang riding mower with a 7hp briggs. It was not getting a spark so I have replaced the points and condensor. there are two wires coming from the end of the condensor out from under the flywheel. one goes into the coil. the other was snipped and not connected to anything. looks like it should go around to the side of the engine. can anybody tell me where this wire should go? thanks!
