An alternator rectifier bridge, built with high-quality diodes. It is a key sub-assembly that converts the alternating current (AC) produced by the alternator into direct current (DC), which is necessary to charge the battery and power the machine's electrical system. This is a cost-effective solution for rebuilding an original alternator.
Aftermarket quality product – an intelligent choice combining excellent quality with an attractive price.
| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 2CX, 3CX, 4CX (with Perkins engines, manufactured before approx. 2005) |
| JCB (Telehandlers) | Loadall (models with Perkins engines, e.g., 520, 525, 530, 540) |
| JCB (Skid Steer Loaders) | ROBOT |

The list above is for reference. It is crucial to ensure that your machine is fitted with an alternator with one of the listed part numbers (e.g., 714/40476).
Charging problems often result from poor electrical connections. Before replacing the rectifier, thoroughly clean the battery terminals and all contacts and cables at the alternator. Use a dedicated contact cleaner for this, then protect the connections with HYPTRON copper grease.
The rectifier is one of the most frequently failing components of an alternator. The failure of even a single diode leads to a drop in charging efficiency, resulting in an undercharged battery and problems with the machine's electrical system.
Replace the rectifier if you notice the following symptoms:
