JLG 1600346 Sevcon Drive Controller
JLG 1600346 Sevcon Drive Controller is a replacement drive controller designed for compatible JLG electric aerial work platforms. The controller manages the electrical drive system and is an important component of the machine’s propulsion and motor control system.
JLG identifies part number 1600346 as “CONTROLLER, SEVCON DRIVE.” The 1600346 module is associated with Sevcon drive systems and is visually identified as a blue drive module in JLG parts documentation.
The 1600346 drive module is used on selected JLG electric scissor lifts and related equipment. Compatibility depends heavily on machine model, country of manufacture, serial number, and the drive module installed on the machine.
RQ Parts supplies OEM-alternative replacement controllers and electrical components for JLG and other major aerial work platform brands.

What Is JLG 1600346?
JLG 1600346 is a Sevcon drive controller used in the electrical drive system of compatible JLG machines.
The drive controller receives control signals and manages the electrical power delivered to the drive motors. It is therefore an important electronic component for machine travel and propulsion functions.
JLG parts documentation specifically distinguishes the 1600346 Sevcon drive module from the later 1001092456 drive module.
Compatible JLG Models
JLG 1600346 has been used on selected electric scissor lift models, including:
- JLG 1230ES
- JLG 1930ES
- JLG 2030ES
- JLG 2630ES
- JLG 2646ES
- JLG 3246ES
JLG parts documentation for these machines identifies 1600346 as one of the drive modules used in the drive system.
However, do not determine compatibility by model name alone.
JLG used different drive modules depending on:
- Machine serial number
- Country of manufacture
- Production period
- Drive system configuration
- Existing drive module
For example, JLG documentation states that USA-built machines before certain serial numbers used the 1600346 Drive Module, while later machines use 1001092456. Belgium-built machines and China-built machines can have different configurations.
Important Compatibility Information
Before purchasing JLG 1600346, verify the drive module installed on the machine.
JLG documentation specifically instructs technicians to identify the drive module by its part number or visual appearance before ordering.
The two commonly encountered modules include:
1600346 — Sevcon Drive Module
1001092456 — Alternative/later Drive Module
The JLG 1600346 module is identified as blue, while 1001092456 is identified as black in JLG parts documentation.
If you are replacing an existing controller, compare the part number on the original module before ordering.
Key Features
Replacement for JLG 1600346
Designed as an OEM-alternative replacement for JLG part number 1600346.
Sevcon Drive Technology
1600346 is identified by JLG as a Sevcon drive controller/module.
Electric Drive System Application
The controller is used as part of the electrical drive system on compatible JLG electric machines.
Supports Machine Propulsion
The drive module is an important component of the electrical system responsible for controlling the machine’s drive motors.
Ideal for Equipment Repair
A practical replacement for damaged or failed drive controllers on compatible JLG electric scissor lifts.
Symptoms of a Faulty Drive Controller
A defective drive controller can potentially cause problems with the machine’s drive system.
Possible symptoms may include:
- Machine will not drive
- Drive functions become intermittent
- Drive motor does not operate correctly
- Drive-related fault codes
- Loss of travel function
- Abnormal drive behavior
- Controller communication problems
- Electrical drive system faults
These symptoms can also be caused by batteries, wiring, motors, contactors, sensors, or other electrical components.
Proper troubleshooting should therefore be performed before replacing the controller.
JLG 1600346 vs. 1001092456
One of the most important considerations when purchasing this part is the difference between 1600346 and 1001092456.
| Part Number |
Drive System |
Identification |
| 1600346 |
Sevcon |
Blue |
| 1001092456 |
Alternative/later drive module |
Black |
JLG parts documentation explicitly shows both modules and states that the correct module must be identified before ordering.
Do not automatically substitute 1001092456 for 1600346 or vice versa.
Always verify the machine configuration and existing drive module.
JLG 1600346 for 1930ES
JLG 1600346 is particularly relevant to older JLG 1930ES electric scissor lifts equipped with the Sevcon drive system.
For USA-built machines, JLG documentation indicates that machines before a specified serial number range used the 1600346 Drive Module, while later machines transitioned to the 1001092456 module.
Therefore, if you are looking for a 1600346 controller for a JLG 1930ES, the machine serial number should be checked before ordering.
JLG 1600346 for 1230ES
The JLG 1230ES parts manual also identifies machines equipped with the 1600346 drive module.
The manual provides separate electrical schematics for machines equipped with 1600346 and machines equipped with 1001092456.
This confirms that the drive controller configuration can vary even within the same JLG product family.
