The Genie 71222GT is a genuine OEM Suppression Diode Wire Assembly designed for Genie GS large-platform scissor lifts, including the GS-3390, GS-4390, GS-5390, and GS-3384. As a direct OEM replacement, this assembly is built to the same electrical specifications as the original component, ensuring correct diode polarity, wire gauge, and connector compatibility straight out of the box. Cross-reference part number 71222GT against your Genie parts manual to confirm fitment before ordering.
Key Features
- OEM Electrical Specification — Manufactured to Genie's original diode rating and wiring spec, so the suppression circuit performs exactly as designed — no guesswork on voltage handling or polarity.
- Direct Plug-In Replacement — Connectors and wire routing match the original harness layout on GS large-platform scissors, allowing straightforward installation without splicing or adapting.
- Confirmed Fitment — Verified for the GS-3390, GS-4390, GS-5390, and GS-3384 scissor lifts, covering the full family of Genie large-platform scissor models.
- Protects Sensitive Control Components — A correctly functioning suppression diode absorbs voltage spikes generated by coils and solenoids, shielding the machine's control board and relays from damage that can be costly to diagnose and repair.
- Electrical Safety Integrity — On aerial scissor lifts, a failed suppression diode can cause erratic control behavior or unintended electrical faults. Installing a genuine OEM assembly restores the designed protection and keeps the electrical system operating as Genie intended.
A suppression diode wire assembly is a protective electrical component wired in parallel with inductive loads — typically solenoids and relay coils — throughout the machine's control circuit. When a coil de-energizes, it generates a reverse-voltage spike that can damage nearby electronics; the suppression diode clamps that spike and safely dissipates it. When this assembly fails or is missing, control boards, relays, and other sensitive components are left exposed to repeated voltage transients that can cause intermittent faults, premature component failure, or unpredictable machine behavior.
