In my haste to finish my conversion and not havng butt connectors I just twisted and taped the wire from the alt to the post in the black box and forgot about it. Years later I had a no start where the battery voltage to the harness was dropping out. I connected a wire from the alt across the engine to the black box post as a temporary fix until I found my poor,oxidized connection near the alt and fixed it with a butt connector. I had never had a 20 or 10 amp fuse blow for the battery+ connection to the harness.
