INSULATOR - 1/0-3/0 GA - BLK (JLG JL840049)

JL840049: A damaged insulator can cause electrical shorts or ground faults in a battery cable circuit. This aftermarket replacement part references JLG catalog number JL840049. The insulator is a non-conductive sleeve that separates a battery cable from surrounding metal surfaces. Its plain mechanical function is to prevent unintended electrical contact between the cable and chassis components. A concrete generic failure consequence is that a worn or missing insulator may lead to cable chafing and eventual short-circuit. Keeping the insulator in sound condition helps maintain electrical isolation in the cable path. Verify the serial number or application, then call (562) 693-7748.
