4. Setup
Follow these steps to set up your TEMGO golf cart battery charger:
- Inspect Charger: Before first use, inspect the charger, cables, and plug for any signs of damage. Do not use if damaged.
- Placement: Place the charger on a stable, dry, and well-ventilated surface. Ensure it is not exposed to direct sunlight or excessive heat.
- OBC Bypass (if applicable): For Club Car DS models from 1995-2010 and Club Car Precedent models from 2004-2014, an On-Board Computer (OBC) bypass wiring cable may be required. This ensures proper charging with the TEMGO charger. Refer to the diagrams below for correct installation. For 2015-Present 48V Club Car Precedent models, no modification is required.
- Connect to Golf Cart: Insert the 3-pin round plug of the charger into the charging receptacle of your Club Car golf cart. Ensure a secure connection.
- Connect to Power: Plug the AC power cord into a standard 100-240V AC electrical outlet.
OBC Bypass Wiring Instructions (for 1995-2014 Club Car DS / Precedent)
If your golf cart falls within the 1995-2014 model years for Club Car DS or Precedent, you may need to install an OBC bypass wire. This modification ensures the charger functions correctly by bypassing the golf cart's original On-Board Computer, which might interfere with modern charging systems.
The bypass wire connects to the following components:
- Fuse and receptacle
- Battery pack (negative terminal)
- Vehicle electrical system
Ensure all connections match the diagram to avoid improper installation. If you are unsure about performing this modification, consult a qualified technician.
5. Operating Instructions
The TEMGO charger features a plug-and-play design for ease of use. Once properly connected, the charging process is largely automatic.
- Initiate Charging: After connecting the charger to the golf cart and then to the AC power outlet, the charger will automatically begin its five-stage charging process.
- Monitor Charging Status: The flexible indicator light on the charger provides real-time status updates:
- Red-green Flash: Standby mode.
- Red Flash: Battery charge is less than 80%.
- Yellow Flash: Battery charge is greater than 80%.
- Solid Green: Battery is 100% charged.
- Automatic Shut-off and Maintenance Mode: Once the battery reaches 100% charge, the charger will automatically shut off and switch to a maintenance (trickle charging) mode. This prevents overcharging and helps maintain battery health.
- Disconnecting: When charging is complete, first unplug the AC power cord from the wall outlet, then disconnect the 3-pin plug from the golf cart's charging receptacle.
Five-Stage Charging Process:
The charger employs an intelligent five-stage charging process to optimize battery life and performance:
- T1: Slow Charge Mode - Initial low current charge.
- T2: Constant Current 1 - Higher current charge phase.
- T3: Constant Current 2 - Continued high current charge.
- T4: Constant Voltage Current Limit - Voltage is held constant while current decreases.
- T5: Trickle Voltage Limiting 2 Charging - Maintenance charge to keep the battery fully charged without overcharging.
6. Maintenance
- Cleaning: Periodically wipe the charger's exterior with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the cooling fan vents are clear of dust and debris.
- Cable Inspection: Regularly check the power cord and charging cable for cuts, fraying, or damage. Replace if necessary.
- Storage: Store the charger in a cool, dry place when not in use. Avoid extreme temperatures.
- Battery Maintenance: Follow your golf cart battery manufacturer's recommendations for battery maintenance.
7. Troubleshooting
If you encounter issues with your TEMGO charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No indicator light | No AC power; Loose connections; Damaged charger. | Check AC outlet and power cord. Ensure all connections are secure. If still not working, contact support. |
| Charger connected but not charging (Red-green flash) | Charger not fully plugged into golf cart; Battery voltage too low; OBC interference (for older Club Car models). | Ensure the 3-pin plug is fully inserted. Check battery voltage. If applicable, verify OBC bypass wiring. |
| Charging is slow | Battery deeply discharged; High ambient temperature. | Allow more time for charging. Ensure adequate ventilation around the charger. |
| Charger gets hot during operation | Normal operation; Blocked cooling fan. | Some heat is normal. Ensure the cooling fan is not blocked and has clear airflow. If overheating persists, disconnect and contact support. |
| Indicator light shows 100% charged too quickly | Battery already partially charged; Faulty battery. | This may be normal if the battery was not fully depleted. If the battery capacity seems reduced, have the battery tested. |
If the problem persists after attempting these solutions, please contact TEMGO customer support.
