Wiring harness BGM ORIGINAL suitable for all Vespa PX models up to year of construction 1982.

Italian version without battery. With this version, the indicators, the horn and all other consumers are directly supplied with power via the AC on-board network. Matching to this is the ignition base plate used on these vehicles with only 3 cables (contact ignition models) or 5 cables (vehicles with electronic ignition).

CONVERSION (WITHOUT BATTERY)
This wiring harness is perfectly suitable for converting vehicles which have a battery ex works to a simple and basic on-board electrical system without battery. For this purpose, the version with all enclosed switches is the best choice (BGM6685KT).

ADVANTAGES OF CONVERSION

• No battery therefore less maintenance
• All consumers function independently of the battery charge
• No corrosion damage due to an overcooked battery/battery acid
• More light output

COMPONENTS REQUIRED FOR THE CONVERSION

• • VOLTAGE REGULATOR
    Basically, the simple 3-pole voltage regulator (G|G|M) is used with this wiring harness
    Most alternators with 5-cables have a round plug. The wiring harness offered here has (as in the Italian original) 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 are in our electrical accessories.
  • IGNITION BASE PLATE /LIMAAs ignition base plate the type with 5-cable is used (recognizable also by the blue and black cable to the single voltage supply).

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