Forklift Electrical Diagnostics
From dead batteries to control system faults, we diagnose and fix electrical problems fast.
What Is Forklift Electrical Diagnostics?
Forklift electrical diagnostics is the process of identifying and troubleshooting problems with the electrical system of your forklift. This includes the battery and charging system, starter motor, wiring, sensors, and electronic control systems. Modern forklifts—especially electric models—rely heavily on electronics, making proper diagnosis essential.
- Battery and charging system testing
- Wiring inspection and repair
- Control system fault code diagnosis
- Sensor and switch troubleshooting
Signs of Electrical Problems
Electrical issues can show up in many ways. Common symptoms include:
- Won't start: No response when you turn the key or nothing happens when you press the accelerator
- Short run time: Battery drains quickly even when fully charged
- Intermittent operation: Forklift works sometimes but not others
- Warning lights: Dashboard fault codes or warning indicators
- Loss of power: Sudden drop in performance or complete shutdown
- Lights or horn not working: Individual electrical components fail
- Slow charging: Battery takes too long to charge or won't hold a charge

Electric vs. IC Forklift Electrical Systems
We service electrical systems on both electric forklifts and internal combustion (propane/diesel) forklifts. While electric forklifts have more complex electrical systems (drive motors, controllers, large battery packs), IC forklifts also have electrical components that can fail—starters, alternators, ignition systems, and sensors.
