| Symptom | Possible Cause | Troubleshooting Step | | :--- | :--- | :--- | | | Blown primary fuse | Replace the 800mA fast-blow fuse located on the primary (input) side of the charger's circuit board. Do not use a higher-rated fuse. | | Crocodile clips or output cable are damaged/frayed | Worn parts | The output cable with crocodile clips can be replaced or repaired by a competent person with electrical knowledge. Ensure correct polarity is maintained. | | Charging current is too low or intermittent | Internal connection issue | The charger's design uses two positive leads from the transformer that are joined internally. A loose connection here can cause problems. Check the solder joints or connections inside the unit (this should only be done by someone with electrical experience). | | Charger suddenly stopped working | Internal component failure | As an older unit, components like rectifier diodes can fail. This typically requires diagnosis by an electronics hobbyist or professional, as the cost of repair may not be economical. |
