Is your Club Car PowerDrive 2 22110 charger not turning on or failing to charge your golf cart? You’re not alone. This popular charger often runs into issues caused by batteries, cables, or the onboard computer (OBC). In this guide, you’ll learn how to troubleshoot it step by step—without wasting time or money.
Before replacing your charger or batteries, try this simple fix: Battery reconditioning method. It can bring dead batteries back to life and help your charger function again.
Understanding the PowerDrive 2 22110 Charger
This charger is designed to work with 48V Club Car systems (typically six 8V lead-acid batteries). It connects to the cart through the round three-pin plug and relies on communication with the OBC (onboard computer) to start charging.
Quick Checklist Before Troubleshooting
- Cart should be in TOW mode
- Battery pack must have minimum voltage (~38V–40V)
- Charger must be plugged into a working AC outlet
- Cables and pins should be clean and firmly connected
Common PowerDrive 2 Charging Problems
1. Charger Does Not Turn On
This is usually due to low voltage or a failed OBC.
- Check AC outlet and charger power cord
- Ensure pack voltage is above 38V—low voltage prevents activation
- Inspect 3-pin plug for dirt, corrosion, or bent pins
- Try charging another cart—if charger works, your OBC may be the problem
Fix: If batteries are too weak to activate the charger, use a manual 48V charger or recondition the pack to bring voltage back up.
2. Charger Turns On, But Does Not Charge
- OBC is not sending the “start” signal
- Charger relay clicks but shuts off immediately
- Blown fuse or open wiring in the charging circuit
Fix:
- Reset OBC (see section below)
- Inspect all battery cables for corrosion or breaks
- Check the inline fuse in the positive battery cable
3. Charger Starts, Then Stops After a Few Seconds
This typically points to an OBC failure or a battery imbalance.
- OBC misreads battery charge status
- One or more bad batteries prevent current flow
- Voltage drops below threshold when charging begins
Fix:
- Check each battery’s voltage individually
- Recondition any weak batteries to restore balance
- If the OBC is bad, consider bypassing it and using a smart charger
4. Charger Clicks Repeatedly or Buzzes
- Relay inside charger is cycling due to faulty voltage detection
- OBC is malfunctioning or miswired
- Loose or corroded battery terminal
Fix:
- Clean all battery connections and terminals
- Perform a full reset of the OBC
- Test the charger on another cart if possible
How to Reset the Club Car OBC
- Switch the cart to TOW mode
- Disconnect the negative battery cable
- Put the cart in reverse and press the accelerator pedal down all the way
- Hold pedal for 30 seconds, then release
- Reconnect the negative battery cable
- Switch back to RUN mode
This reset clears errors and forces the OBC to recalibrate.
Battery Voltage Guide (48V System)
| Total Pack Voltage | Charge Level |
|---|---|
| 50.9V | 100% charged |
| 48.4V | 75% charged |
| 46.9V | 50% charged |
| 45.3V | 25% charged |
| 44V or below | Needs charge or reconditioning |
If your battery pack is below 44V, the charger may not activate. Reconditioning your batteries is a smart way to restore lost capacity.
When to Replace the Charger
Only replace the PowerDrive 2 22110 if:
- You’ve verified the AC outlet is working
- The OBC reset did not help
- Another charger works on the same cart
- Your unit shows physical damage or burnt smells
New chargers can cost $300–$600, so it’s best to rule out all other issues first.
Preventive Tips
- Charge after every use, even for short rides
- Keep the charger and plug dry and clean
- Store the cart in TOW mode when not in use
- Check battery water levels monthly (for lead-acid)
Conclusion
The PowerDrive 2 22110 charger is a reliable unit—but it depends on battery voltage and a working OBC to function properly. Most problems are related to low voltage or poor connections, not the charger itself. Start by testing your pack and resetting the system before considering costly replacements.
