My car ran good for six months. Went for a drive car died. It has a two wire alternator that is still wired to an external voltage regulator. The car will start if the wires are removed from the alternator. There is a fuse wired into the positive terminal on the power wire to the alternator. When alternator is in circuit that fuse blows. Car has new ignition switch and a new relay for the horn. Any info is appreciated.
