INSULATOR (Nissan NICK1705139)

A worn insulator can allow electrical leakage or short circuits in the system. The insulator serves as a non-conductive barrier that isolates electrical components from surrounding metal surfaces. This aftermarket replacement part references Nissan catalog number NICK1705139. Its primary function is to prevent unintended current flow by physically separating conductors. When an insulator fails, it may cause intermittent electrical faults or complete system shutdown. Keeping the insulator in sound condition helps maintain reliable electrical isolation under normal operating conditions. Verify the serial number or application, then call (562) 693-7748.
