| Symptom | Likely Cause | Solution (Based on Wiring Diagram) | | :--- | :--- | :--- | | | Internal DC fuse blown or loose B+ connection. | Check the fuse board. Check the large reverse polarity fuses. | | Battery won’t charge, but 12V loads work | Reverse polarity fuses are blown (often due to installing battery backwards). | Replace the two 30A or 40A fuses near the DC output. | | Converter hums loudly and gets hot | Shorted battery cell or excessive DC load (>55A). | Disconnect battery; if hum stops, battery is bad. | | Voltage reads over 15V at battery | Shorted transistor/regulator (dangerous). | Replace immediately. Overvoltage boils batteries and destroys LEDs. | | No AC power to converter (breaker trips) | Short in transformer or incorrect wire gauge. | Check AC input wiring. The unit may be internally shorted. |

When your RV is plugged into 120V shore power, the Centurion CS 2000 performs two primary roles: | Symptom | Likely Cause | Solution (Based
The AC side is straightforward. You will find a junction box attached to the converter housing. | | Battery won’t charge, but 12V loads
Feeds the second fused 12V DC circuit (usually the water pump or furnace fan).
The back of the CS 2000 features a colored wire harness that distributes 12V DC power throughout the camper and connects to your auxiliary battery.
Disconnect the negative (-) cable from your house battery bank to eliminate all 12V current.
