Carefully observe the polarity markings before disconnecting any wires Red usually indicates positive (+), black or bare metal indicates negative (–), but always verify the labels Document the terminal layout with a smartphone photo or adhesive labels for foolproof reconnection Start by removing the ground (–) cable, and finish by attaching it last to prevent arcs.
