Power Leads

Power leads deliver high-current electricity from the battery to starting, charging, and accessory systems. Typically constructed of heavy-gauge, corrosion-resistant copper cable with crimped or cast terminals, they feature insulation rated for high temperatures and voltage. Positive leads are often covered in a distinct color (typically red) for identification and safety. Applications include battery-to-starter connections, alternator output, and main grounding straps. Terminal types vary by application, encompassing ring, flag, and threaded designs for secure connections. Proper lead sizing is critical to minimize voltage drop and ensure component functionality.
