Rectifier -BGM ORIGINAL DIY Kit- Vespa VNB1T, VBA1T, VBB1T, GL (VLA1T), SS180 (VSC1T - models with battery), GT (VNL2T), Super ( fitting for Vespa Rally 180 VSD1T 1969, 10,3 PS, 7,6 kw

Do-it-Yourself Kit as replacement for the original selenium rectifier which is no longer available.
This was used in the Vespa models with battery before 1979 (Vespa VNB1T, VBA1T, VBB1T, GL (VLA1T), SS180 (VSC1T), GT (VNL2T), Super (VNC1T, VBC1T), Rally200, Sprint (VLB1T).

If you want to keep the original optics you can use the kit offered here:
A modern Silizum bridge rectifier in the old case of the original selenium rectifier.
The modern rectifier works much more effective than a selenium rectifier which is damaged by overageing.

Our kit contains a universal rectifier which converts the incoming alternating current into a direct current and which is also very easy to wire.
It has two alternating current inputs (marked with a shaft) as well as two direct current outputs (`+` and ` -`)

CONNECTION
If the assignments / cable colours of the original selenium rectifier are unknown, it is very helpful to have a circuit diagram of the vehicle at hand (in our online shop these are usually available for download with the corresponding cable harnesses).
The assignment of the AC input is very simple, there are no possibilities to reverse the polarity here. Connect the `+` output of the direct current output with the positive pole of the battery. Connect the output to the vehicle body or the negative pole of the battery.

NOTE
The rectifier provides the DC current required for battery charging. It has no voltage regulator function, i.e. it cannot reduce 12Volt to 6Volt or similar.
It should also only be used with the original self-regulating alternator systems (such as the vehicles listed above), in which the alternator only produces as much power as is required by the vehicle. Modern alternators (e.g. type Vespa PX) produce a very high excess power (at full throttle over 40Volt) which would destroy any battery immediately.
