The genuine Western 56131K-2 Motor Relay serves as the primary heavy-duty electrical switch on your truck-side setup. This premium 12V solenoid safely channels high-amperage starting current from the vehicle battery directly into the primary plow pump motor. Consequently, replacing a clicked out or stuck relay prevents sudden power loss. It also stops your pump motor from running continuously or draining your truck battery down during long night routing shifts.
This authentic vehicle-side component incorporates a standard 4-terminal architecture. Because it handles extreme electrical surges smoothly, it protects your interior cab controller circuits from high-voltage back-feed or melting damage. Furthermore, the robust metal mounting bracket grounds directly to the vehicle chassis to establish a secure electrical loop. Therefore, your hydraulic system triggers instantly whenever you hit a raise or angle button on your remote.
Our warehouse packages this factory replacement assembly as a standalone service kit. This package houses the primary 12V coil solenoid block alongside fresh high-tensile locking nuts and copper washer terminals. Because this model features upgraded internal contact disks, it resists premature terminal arcing and pitting through sub-zero deep-freeze conditions. Installing genuine parts ensures your fleet operations remain completely reliable all winter long.
