Rectifier (2DS 506)
A rectifier (19-1715 / 49072) that converts AC charging current to DC, appearing in electrical equipment listings from 1969-1972.
This is a rectifier, part number 19-1715 (also listed as 49072), and it shows up in the electrical equipment sections of the parts books across several plates. The manufacturer tag on this one says Amal, but that's off the mark - a rectifier is an electrical component, not a carburetor part, so don't go looking for it near the mixing chamber. It's more likely a Lucas-type piece even though our records don't spell that out plainly.

A rectifier's job on these old British bikes is to take the AC current coming off the alternator or dynamo and convert it to DC so the battery can actually charge properly. It's a small metal-finned unit, usually tucked in under the seat or near the battery, wired inline with the charging circuit.
