The Multiquip 38501MGP003 is a genuine OEM Power Relay Micro ISO 4P Blue MD105 designed for the MD105 mid-sized hydraulic ride-on power trowel. Sourced directly from Multiquip, this relay matches the original electrical specification for correct circuit operation and reliable switching performance. Confirm your model and part number before ordering to ensure a direct installation match for your MD105 trowel.
Key Features
- Correct Switching Specification — Genuine OEM construction ensures the relay operates at the proper voltage and current rating required by the MD105 electrical system, so the controlled circuit activates and de-activates cleanly every time.
- Micro ISO 4-Pin Configuration — The standard ISO 4-pin micro relay footprint drops directly into the OEM relay socket without re-pinning or adapter wiring.
- Blue Housing Identification — The blue casing matches the original component for fast visual identification during inspection or replacement on the MD105 control circuit.
- Hydraulic Trowel Compatibility — Engineered specifically for the MD105 mid-sized hydraulic ride-on trowel, keeping the machine's electrical and hydraulic control circuits functioning as intended.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component under part number 38501MGP003, giving you confidence that the replacement matches the original design intent exactly.
A power relay is an electrically operated switch that allows a low-current control signal to open or close a higher-current circuit within the machine. On hydraulic ride-on trowels like the MD105, relays govern key functions such as blade speed control, drive engagement, and safety shutoff circuits. When a relay fails, the circuit it controls may stop responding entirely, respond intermittently, or remain energized when it should not be — all of which can affect trowel operation and operator safety. Replacing a faulty relay with the correct OEM part restores predictable, code-matched switching behavior to the affected circuit.
