Sparking When Connecting Battery Cables Question

When I try to attach the battery cables to the 6 Volt battery in my 1929 Model A Ford, there’s a noticeable increase in sparking when I make contact with the posts. I don’t recall this happening before. Could you suggest possible reasons for this? Is it safe to proceed with securing the cables, or might it harm the electrical system? I appreciate any assistance you can offer.

Answer:

Please ensure that you’re not accidentally connecting the positive cable to the negative ground. Also, inspect to make sure that there’s nothing touching either of the two battery posts, such as the battery hold-down clamps, shorts, or any other grounds. Once you’ve checked these aspects, please let me know what you find. – Lyle Meek, 1997 Technical Director
