Hopefully some others will offer help. All my old tractors have points ignition. Starting from that I would read carefully any instructions you have. Also remember that if the tractor still has a 6 volt positive ground system , the red is positive, and has to connect to the positive side which is the ground. The positive battery cable would be connected to ground, and.the black wire would be the negative and connected to the starter side of the system. An ohm meter will tell you. If the tractor has a 12 volt system the negative and positive battery cables will be reversed. The net may help you. Search for any folks that have installed your pointless system. YouTube videos have helped me with problems.
