Symptoms of Poor Battery Contact in Cars?
1 Answers
Symptoms of poor battery contact in cars: The battery terminals become hot to the touch or produce sparks. The following solutions can be applied: 1. Re-tighten: Clean the battery terminals of any dirt and then re-tighten them. 2. Add a metal shim: If the battery terminal clamp bolt remains loose after tightening, a metal shim can be added as a temporary fix. Cut a piece of copper or iron sheet of appropriate size, wrap it halfway around the battery terminal, then reattach the cable connector and tighten the clamp bolt. 3. DIY clamp: If half of the terminal clamp is broken: You can make a clamp from iron, aluminum, or copper sheet, or use a capacitor clamp as a substitute, and secure the unbroken half of the original clamp and the DIY clamp together with a bolt. If the terminal clamp is completely broken: Cut off the terminal clamp and directly fasten the copper wire from the power harness to the DIY clamp. If the terminal clamp breaks at the base: Use a copper gasket from an old cylinder head to make a protective cap, fit it over the soft copper wire of the power harness, drill a hole in the cap, and then secure it together with the original terminal clamp.
