The Multiquip 802378 is a genuine OEM 12 VDC Relay designed for WTB-16, WTB-16PD, and AR14H series equipment. As a direct Multiquip OEM component, this relay is built to the exact voltage and switching specifications required by the original electrical system. Verified fitment covers the WTB-16 and WTB-16PD Whiteman track buggies as well as the AR14H asphalt ride-on roller, making it the correct choice when restoring electrical control circuits on these machines. Order with confidence using part number 802378 to ensure you receive the right component for your application.
Key Features
- Correct 12 VDC Rating — Matches the operating voltage of the original electrical circuit, ensuring proper coil activation and contact switching without risk of over- or under-voltage conditions.
- Genuine OEM Component — Sourced directly from Multiquip, this relay carries the same part specification as the unit installed at the factory, so it connects and seats exactly as the original did.
- Confirmed Fitment — Verified for WTB-16, WTB-16PD power buggies and the AR14H ride-on roller; use part number 802378 to confirm compatibility before ordering.
- Restored Electrical Control — A failed relay can disable critical switched circuits — machine drive, lighting, or accessory controls — and a correctly rated replacement restores full electrical function immediately.
- Electrical Safety Assurance — Using the correct OEM-spec relay prevents unintended circuit faults, contact arcing, or coil failure that can occur when an incorrect relay is substituted in a 12 VDC control system.
A relay is an electrically operated switch that uses a low-current control signal to open or close a higher-current circuit within the machine. In equipment like the WTB-16 power buggy and AR14H roller, relays manage key switched functions — routing power to drive systems, safety interlocks, or auxiliary components on command from the operator or a control module. When a relay fails, the circuit it controls will either remain permanently open (leaving a system inoperative) or permanently closed (causing unintended operation), both of which can halt work and create unsafe conditions. Replacing a worn or failed relay with the correct 12 VDC unit restores normal switching behavior and full machine control.
