The Genie R661490GT is a genuine OEM Relay, 12V DC, 30A NO OR designed for Genie and Terex light towers and select boom lifts. As a direct OEM replacement sourced through Genie's authorized parts supply, this relay matches the original electrical specification for the machines it serves. Compatible equipment includes the AL4, AL4L, AL4000, AL5, AL5L, AL5 with Vertical Mast, AL5000, RL4, RL4000, TML-4000, and the TZ-50 articulating boom — cross-reference part number R661490GT against your machine's parts manual to confirm fitment for your specific unit.
Key Features
- Genuine OEM Electrical Spec — Rated at 12V DC and 30A, this relay matches the original switching specification to ensure correct circuit behavior across the machines it serves.
- Direct OEM Replacement — Supplied by Genie as an authorized OEM part, this relay installs directly in place of the original without modification.
- Broad Equipment Compatibility — Fits multiple Genie and Terex light tower families — including the AL4000, AL5000, RL4000, and TML-4000 — as well as the TZ-50 articulating boom lift.
- Restored Switching Function — A faulty relay can cause circuits to fail to energize or de-energize correctly; replacing it with this OEM part restores proper electrical switching and keeps affected systems operating as designed.
- Operational Safety — Relays control the activation of key electrical circuits. Using the correct OEM-rated relay helps ensure switching performance meets the original design intent for your machine.
A relay is an electrically operated switch that uses a low-power control signal to open or close a higher-current circuit. On light towers and boom lifts, relays manage the activation of electrical loads across the machine. When a relay fails — due to worn contacts, coil burnout, or corrosion — the circuit it controls may become unresponsive, causing equipment to behave erratically or fail to start. Replacing a failed relay with the correct OEM part restores normal switching behavior and prevents further electrical faults downstream.
