Daewoo Forklift G30P-3 Overview
The Daewoo G30P-3 is a mid-size internal combustion forklift designed for industrial material handling, warehouse operations, and outdoor logistics. Manufactured during the early 2000s, this model features a 3-ton lifting capacity, pneumatic tires, and a gasoline or LPG-powered engine. Daewoo Heavy Industries, which later merged into Doosan Infracore, was known for producing durable and cost-effective forklifts that were widely exported across North America, Europe, and Asia.
The G30P-3 incorporates a relatively simple electrical system compared to modern CAN-bus forklifts. However, locating a wiring diagram for this model can be challenging due to the age of the machine and the corporate transitions that followed its production.
Terminology Notes
After Daewoo’s forklift division was absorbed into Doosan, many legacy service manuals were archived or discontinued. Dealers may no longer stock printed manuals for the G30P-3, and online repositories are fragmented. Some manuals exist in PDF format but are often behind paywalls or hosted by third-party sellers.
Owners seeking wiring diagrams often face these issues:
In Florida, a technician restoring a G30P-3 forklift searched for a free wiring diagram and found that most sources required payment or registration. He eventually located a partial schematic in a used service manual purchased from an equipment auction site. The diagram helped him trace a faulty ignition wire that was preventing the starter from engaging.
In British Columbia, a warehouse mechanic discovered that the instrument cluster wiring had been modified by a previous owner. Without a diagram, he spent hours tracing wires manually. He later found a scanned copy of the electrical section from a similar Daewoo model, which provided enough guidance to restore the dashboard functions.
Recommendations for Owners and Technicians
Finding a wiring diagram for the Daewoo G30P-3 forklift requires persistence and creativity. While official sources may be limited, technicians can often piece together enough information from similar models, auction manuals, and community forums to complete repairs. In legacy equipment, documentation is as valuable as the tools themselves—and sometimes just as hard to find.

Terminology Notes
- Wiring Diagram: A schematic representation of electrical circuits showing wire colors, connector locations, and component relationships.
- Service Manual: A technical document containing maintenance procedures, specifications, and diagnostic charts.
- Ignition Circuit: The electrical path that controls engine start, including the key switch, starter relay, and solenoid.
- Instrument Cluster: The dashboard panel displaying fuel level, engine temperature, and warning lights.

Owners seeking wiring diagrams often face these issues:
- Limited Dealer Support
Many Daewoo dealers transitioned to Doosan branding and may not carry legacy documentation.
- Model Number Confusion
The G30P-3 may be listed under alternate designations depending on region or engine type.
- Language Barriers
Some manuals are available only in Korean or Spanish, depending on the export market.

Recommendations for Owners and Technicians
- Search Using Full Model and Serial Number: Include engine type and fuel system for accurate results.
- Contact Doosan Forklift Dealers: Some retain access to archived Daewoo manuals.
- Explore Equipment Auction Sites and Forums: Manuals often surface in resale listings.
- Use Similar Model Diagrams as Reference: Daewoo forklifts share common wiring layouts across models.
- Label and Photograph Existing Wiring Before Repairs: Helps reconstruct circuits if diagrams are unavailable.
