Multiquip 45357 MVEC Fuse Box Assembly - OEM Replacement Part for Power Trowels

The Multiplexed Vehicle Electrical Center (MVEC) fuse box provides centralized circuit protection and power distribution for ride-on power trowel electrical systems. This CAN bus-controlled electrical center manages both switched and un-switched power circuits, protecting critical components including hydraulic cooler fans, lighting systems, spray pumps, seat switches, hand controls, and the MCU controller through 16 individual fused circuits rated from 5 to 30 amps.

The MVEC fuse box includes integrated power relay modules (PRM) for both switched and un-switched power distribution, connecting to the MC43 controller via a 12-pin CAN connector (J3). It features dual DTM connectors (DTM04-8PA and DTM06-8SA) for ignition-switched power and integrates directly with the +12 VDC battery system and ignition switch circuit. The unit provides dedicated circuit protection for engine ECU power, OBD service tool connections, and fuse box communication power, making it essential for diagnosing electrical faults and maintaining proper trowel operation.
