Kabelbaum BGM ORIGINAL passend für alle Vespa PX Modelle bis Baujahr 1982

Convert your old Vespa PX with battery now easily

A modern electrical system without battery on your scooter does not destroy the appearance, it is an invisible and economical increase in safety and comfort, because

  • Without a battery, there is no need to purchase / replace and maintain the battery
  • Your electrical system and all consumers function independently of the battery’s condition or charge level
  • You efficiently prevent corrosion damage to your Vespa PX caused by an overcooked battery/battery acid
  • Significantly more safety due to increased light output = increased visibility = better being seen & and better seeing

Conversion wiring harness for all Vespa PX models until 1982

This wiring harness is perfect to convert your Vespa PX, which has a battery ex Piaggio factory, to a modern and maintenance-free on-board electrical system without battery. For this purpose, we offer an inexpensive and practical set with all the necessary new switches and ignition lock(BGM6685KT). Wiring harness in set with switches

Additionally, for a replacement / restoration, this is the PX wiring harness in the Italian version for models without battery. On this model, the turn signals, the horn (so-called “snare”) and all other consumers are supplied with power directly via the on-board AC system. The ignition base plate used on these vehicles has only 3 cables (contact ignition models) or 5 cables (vehicles with electronic ignition). Wiring harness single without switch

Vespa PX battery-free : Conversion without battery

For the conversion of your scooter to the modern electrical system, you need the following parts and save the battery, the wintering and the care/maintenance of the vehicle battery in the future

  • VOLTAGE REGULATOR In general, the simple 3-pole voltage regulator (G|G|M) is used with this wiring harness (e.g. 9100001). The 5-pole voltage regulator (A|A|B+|G|M) originally used on vehicles delivered from the factory with battery can still be used. Only the connections B+ and G remain unassigned (formerly charging current for the battery). A better alternative is the compact and powerful BGM Pro voltage regulator(BGM6690). This can, for example, also supply a USB socket with 12V DC voltage for charging the mobile phone/navi, etc.
  • IGNITION / IGNITION BASE PLATE /LIMA The type with 5-cables is used as ignition base plate (also recognisable by the blue and black cable for the single voltage supply). The original 7-cable Lima of the models with battery can no longer be used. However, due to their age, these often show damage to the cable insulation anyway. Conversion to the more powerful ignition base plate of the later Lusso models (e.g. BGM8025N or BGM8032N) is therefore highly recommended. This increases the total light output of the AC network considerably, as no more current is diverted for battery charging. Thus, even old PX models can be equipped with a 35/35W lamp. Most alternators with 5-cables have a round plug. The wiring harness offered here has (as in the original Italian) 6.3mm flat plugs. Here, either the wiring harness can be converted to a round plug or the ignition base plate can be converted to a flat plug. The necessary parts can be found in the accessories.
  • BLINKING RELAY The models with battery use a DC (direct current) flasher relay. After conversion, an AC (alternating current) flasher relay is required (e.g. 1195703).
  • INSTRUCTIONS / WIRING DIAGRAM The following instructions / wiring diagramwill help you to connect the cables .

Checklist: Spare parts / parts that are connected to the wiring harness

To make sure everything works, you should go through this list and check if your old parts are still OK. If not, you can order them directly from our Vespa Shop via the link:

*9512115 ? 9520072 + 9520074 / **9512027 ? 7675200 + 7675201

CONCLUSION: Absolutely sensible conversion to modern, more powerful and maintenance-free electrics
