Product Overview: Genie Solenoid Coil (Part #77709GT)

24V Solenoid Valve Coil 77709GT For Genie GS1532 GS1930 GS2046 GS2646 Z-45/25

The Genie 77709GT is a genuine OEM (Original Equipment Manufacturer) 24V DC solenoid valve coil. It is a critical electromechanical component designed to reliably control the hydraulic system on various Genie aerial work platforms. This coil converts electrical energy into magnetic force, which actuates the solenoid valve, directly managing the flow of hydraulic fluid to control functions like lifting, lowering, and steering.

Key Features & Specifications

• Genuine OEM Part: Manufactured to Genie's exact specifications, ensuring perfect fit, optimal magnetic pull, and reliable performance.

• Voltage: 24 Volts DC - Matches the electrical system of the compatible Genie scissor lifts.

• Part Number: 77709GT - The essential identifier for correct ordering and compatibility.

• Duty Cycle: Typically rated for 100% continuous duty, meaning it can be energized for extended periods without overheating.

• Construction: Features a high-temperature epoxy encapsulation or plastic housing to protect the internal windings from moisture, dirt, chemicals, and physical impact, which is crucial for the harsh environments of construction and industrial sites.

• Connection Type: Usually equipped with a DIN-style connector for a secure, waterproof, and quick connection to the machine's wiring harness.

Core Function & Application

This solenoid coil slides onto the stem of a specific hydraulic solenoid valve on the machine. When the operator presses a control button (e.g., "UP"), the machine's control system sends 24V DC power to this coil. The coil then generates a magnetic field, which pulls the valve's internal plunger. This action shifts the valve, directing pressurized hydraulic oil to the appropriate cylinder or motor, resulting in the commanded movement (e.g., the scissor lift rising).

Its primary application is to repair or replace a faulty coil that causes operational failures.

Compatibility List

This specific part number (77709GT) is certified and engineered for the following Genie models:

• Genie GS-1532 Scissor Lift

• Genie GS-1930 Scissor Lift

• Genie GS-2046 Scissor Lift

• Genie GS-2646 Scissor Lift

• Genie Z-45/25 Articulated Boom Lift

It is crucial to verify your machine's model and serial number before ordering.

Symptoms of a Failing Solenoid Coil

You may need to replace this coil if you experience any of the following issues:

• Complete Function Failure: A specific machine function (e.g., lift up, drive forward) does not work at all.

• Intermittent Operation: The function works sporadically or only when the coil is tapped/jiggled.

• Overheating: The coil is excessively hot to the touch, often accompanied a burnt smell. This indicates internal shorts.

• Visible Damage: Cracks in the housing, melted epoxy, or damaged electrical connectors.

• Electrical Faults: The machine's diagnostic system may show a fault code related to an open circuit or short circuit on a specific valve circuit.

Why Choose a Genie OEM Coil?

• Precise Magnetic Strength: Ensures the valve shifts crisply and completely for reliable operation.

• Correct Impedance: Matches the machine's electrical system, preventing damage to the control PCB (printed circuit board).

• Sealing and Durability: Built to Genie's standards for water and dust resistance, ensuring longevity on the job site.

• Safety and Reliability: Using a non-OEM coil can lead to improper valve operation, potential machine malfunction, and safety hazards.
