How Can You Read Charger LED Codes for Your Golf Cart Model?
Understanding your golf cart charger’s LED codes helps diagnose charging status and faults efficiently. While codes vary by manufacturer, solid green typically means a full charge, flashing red signals errors, and yellow lights indicate charging phases. Consulting your model’s manual is best, but this guide provides common LED meanings and troubleshooting steps for popular chargers, including Delta-Q and E-Z-GO.
What Do Common Charger LED Colors and Patterns Mean?
Most chargers share standard LED indicators:

- Solid Green: Charge complete; battery in maintenance mode.
- Flashing Green: Battery nearly full; topping off.
- Solid Red: Charging active.
- Flashing Red: Fault or charging error (poor connection, low voltage, bad battery).
- Solid Yellow/Amber: Bulk charging phase (initial stage).
- Flashing Yellow/Amber: Absorption phase (80-100% charged).
- Flashing Red & Green: Error or poor battery health.
- No Light: Charger off, no power, or disconnected.
Interpreting these signals can guide your next step—whether to keep charging, check connections, or service batteries or charger.
How Do Model-Specific Charger LED Codes Differ?
Many manufacturers add model-specific flash codes:
- Delta-Q Chargers (used on E-Z-GO and others) use red flashing numbers for faults: 2 flashes indicate voltage too high/low; 3 flashes mean charging timed out; 4 flashes suggest battery voltage did not rise; 6 flashes signify internal charger faults.
- E-Z-GO Chargers may flash green for slight charge, red for very low battery, and solid light for full charge.
- Minn Kota Chargers use solid yellow for bulk, flashing yellow for absorption, and flashing or solid green for maintenance mode.
Checking your charger’s manual for these specific codes ensures accurate diagnosis.
What Are the First Steps When a Fault Code Appears?
- Check All Connections: Ensure charger plug and battery terminals are secure and clean.
- Verify Charger Power: Make sure the charger is plugged into a live outlet.
- Consult the Manual: Identify what the flashing pattern means for your charger model.
- Test Battery Voltage: Use a multimeter; low voltage can prevent charging start.
- Contact a Technician: If issues persist, a professional can determine if the battery or charger requires replacement.
How Can Understanding LED Codes Improve Golf Cart Maintenance?
Recognizing your charger’s LED signals allows early fault detection, preventing battery damage or charger failure. It helps maintain battery health by confirming correct charging stages and identifying when batteries are fully charged or require service. This keeps your golf cart reliable and extends battery lifespan.
