"BGM ignition base plates and ignition kits are the solid basis for a high-quality engine.
The strong alternator guarantees perfect light output, the HQ ignition components a clean and powerful running engine, the BGM pole wheel an extremely quiet engine run.
Ideal for upgrading aging, contact controlled electrics to a contemporary, maintenance-free high performance ignition.
advantages:
- High light output due to maximum number of windings
- Proven excitation coil with copper plate for highest reliability
- Pickup with carbon barrier layer for a clean ignition pulse
- Cleanly processed light coils
- High quality solder joints
- Grey and black bougier tube
- Adequate cable length for individual cabling
- Combinable with additional modules (PiFi, Kytronic,Agusto)
In comparison to a conventional electronic ignition, the BGM ignition base plate has specially combined coil windings. This significantly improves the efficiency of the alternator.
Available individually or in a set:
- Base plate V4.0
- Base plate V4.0 + BGM Polrad
- Base plate V4.0 + BGM Pole wheel + BGM Controller + orig. Piaggio/Ducati CDI
AC/DC?
The alternators are available as AC and DC version:
- AC = alternating current = light via alternator
- DC = direct current = light via battery
AC
For conversion to a good electronic ignition, the AC version is best suited. In principle, the on-board electrical system remains as it was conceived by Innocenti, although it is best to use a fresh wiring harness.
DC
Conversion to DC only makes sense if a sufficiently dimensioned battery is installed at the same time (from 5Ah). Here, the entire luminous flux feeds only the battery via a so-called full wave regulator. This then supplies all consumers. The AC set contains the required full wave regulator, please order the battery separately. The advantage lies in the perfect light without flickering, even in idle gas. The disadvantages are the required battery, the high charging losses in the lower speed range (regulator gets very warm) and the necessary modifications of the wiring harness.
TIP: The DC ignition can also be used as AC ignition at any time. For this purpose, connect the red/yellow cable to earth. The yellow cable must then be connected as a live cable to a conventional voltage regulator (e.g. BGM6690).
FOR WHICH ENGINES?
The ignition kits are available for both crankshaft types of the Lambretta Series 3 models:
- Small alternator cone: LI, LIS, SX, TV
- Large alternator cone: GP/ DL
Note: The BGM ignition has been carefully designed and harmonizes excellently with all common ignition components, especially with the BGM pole wheel.
To ensure that the BGM ignition always finds optimum conditions, we have included spacer plates for the pickup with Version 4.0. Thus the base plate can also be combined with pole wheels whose trigger surface height (tear-off surface of the pick-up) lies outside the standard (e.g. AF pole wheels) or if tolerances of the engine housing and/or crankshaft overlap unfavourably."
