Genie Scissor Lift Parts 121615 121615GT 12V Throttle Solenoid for Genie Lift S-60 S-65 S-80 S-85

Product Overview: 12V Throttle Solenoid (Part #: 121615 & 121615GT)

This product is a 12-Volt Throttle Control Solenoid, a critical engine management component for specific Genie scissor lift models. It is supplied as part numbers 121615 and 121615GT (which may indicate a kit or updated version).

Primary Function:
This solenoid acts as an electrically controlled valve to regulate the engine's throttle. Upon receiving a signal from the lift's control system, it precisely modulates the flow of hydraulic pressure or provides a mechanical pull to adjust the throttle position, thereby controlling the engine's RPM.

Key Features & Specifications:

• Voltage: 12V DC

• Function: Electro-hydraulic or electromechanical throttle actuator.

• Design: Typically a compact, cylindrical metal body with an integral plunger and electrical connector terminals.

• Mounting: Features standard mounting brackets or bosses for secure installation on the engine or hydraulic manifold.

• Sealing: Often includes integrated O-rings or gaskets to prevent hydraulic fluid leaks and protect against environmental contaminants.

• Durability: Engineered for the demanding conditions of construction equipment, with resistance to vibration, temperature fluctuations, and exposure to fluids.

Compatibility & Application:

This solenoid is a genuine/replacement part designed for use in the following Genie scissor lift models:

• Genie S-60

• Genie S-65

• Genie S-80

• Genie S-85

Machine Type: Rough Terrain Scissor Lifts (These models are typically boom lifts, and the S-series are large rough-terrain scissor lifts with engine-driven systems).

Purpose & Operational Role:

This component is essential for the "Throttle Up" or "High-Speed" function of the lift. Its primary roles are:

1. Engine Speed Control: It allows the operator to increase engine RPM from the platform controls, providing greater hydraulic power for simultaneous driving and lifting operations or for operating on inclines.

2. Dual-Speed Operation: It enables the switch between a standard, fuel-efficient engine speed and a high-power mode for demanding tasks.

3. System Integration: It serves as the crucial link between the lift's electrical control system and the engine's mechanical throttle, ensuring responsive and reliable power management.

Common Symptoms of a Failing Solenoid:

• Loss of High-Speed Function: The "Throttle Up" or "High-Speed" switch on the platform does not increase engine RPM.

• Erratic Engine Behavior: The engine may surge or stumble when the throttle is engaged.

• Electrical Faults: Blown fuses or diagnostic trouble codes related to the throttle circuit.

• Hydraulic Leaks: Visible fluid leaking from the solenoid body (if it is a hydraulic type).

• Physical Damage: A cracked housing, damaged connector, or a stuck plunger.

Installation Note: Replacing this component requires technical knowledge of the lift's hydraulic and electrical systems. It is strongly recommended that installation and any necessary system bleeding be performed by a qualified service technician to ensure proper and safe operation.
