Fits ALL BMW 2-valve twins made from 1970 - 1995 and comes complete with new wires.

This high output voltage rectifier has a massive heat sink for the large-capacity diodes, giving even better cooling to ensure maximum reliability.

The new wires get rid of the brittle, tired originals that can limit charging performance and cause overheating. The new red wire provides a low resistance path for the charging current to return to the battery, a frequent weakness on many ageing machines.

Please note: There are 2 standard mounting methods used by BMW. The diode board will either be mounted on rubbers ELA58131 or directly mounted to raised pillars on the front engine casing. Larger diameter earth wires are provided for installation on rubber mounted applications, since the original earth wires are often inadequate. On diode boards mounted directly to the engine, all four mounting points are at earth potential.

This is the same diode board that comes with the 600W charging system, ELA60001, so it's definitely over-engineered for the stock 20 amp or less charging system. See the picture of ELA60000 for guidance on wiring.

Note: The earth wires are only required if the rubber diode board mounts are used.
