Wiring harness conversion for electronic ignition on Vespa V50, Sprint and Rally

Conversion wiring harness for conversion to Vespatronic ignition system in Rally, Sprint, VBB, Super, VNA, VNB, etc.

Converting to a more modern generator/ignition type is a tried and tested means of being safer and more durable on the road. The non-contact CDI ignitions are almost indestructible and reliable, and the light output with a modern, regulator-supported on-board electrical system is also many times higher, as not only is the voltage increased from 6 volts to 12 volts, but the ignition base plate can also generally produce more power

. To do this, it is necessary to adapt the wiring harness, as in a modern electrical system the alternators have all the light coils connected in series for maximum power output and there is only one current-carrying cable as an output for the on-board voltage. This is then routed to the voltage regulator, which limits the on-board voltage to a constant 12-13 volts. This effectively prevents the dreaded domino effect of the old electrical system, where all the bulbs burn out one after the other after a single one fails. The current is only conducted to the individual consumer after the regulator. This technology also allows a very powerful alternator such as our BGM ignition base plate to be used, which guarantees a high light output and ignition power even at low engine speeds.

To use such an alternator in the old chassis, you therefore need a suitable wiring harness. Our conversion wiring harness is exactly what you need and can also be used universally. It is based on an electrical system that has been reduced to the bare essentials and powers the horn/snare, headlights/dipped headlights and tail/brake lights. A flasher relay can be fitted as an option; the wiring harness is already prepared for this. In conjunction with our BGM 12Volt voltage regulator, this results in a very modern on-board electrical system which, in addition to a brilliant and powerful light output, also has gimmicks such as a DC output for charging a smartphone or navigation device, for example.

When using our conversion wiring harness, a battery is no longer required. Any existing 6V snare can continue to be used as it can handle the occasional 12V without any problems. Further technical information can be found in our wiring diagram.

• Reliable electronic ignition - no more contact adjustment
• Very high light output with 12V on-board voltage
• Optional direct current for charging a smartphone or navigation device

Please note: In very old vehicles, the larger cable cross-sections used in the conversion wiring harness can lead to space problems. This is particularly the case in the area of the tube channel for the rear light and in the steering head area. For safety reasons, however, we do not want to use smaller cable cross-sections.
