Lambretta LD Late Model HT Terminal Block

In the event that the flywheel magneto should be removed from the engine, care must be taken when reassembling to connect circuit wires exactly to their terminals in the
flywheel socket ( Look at fig. 85).

If there is a faulty connection, the fact will be apparent by reason of a very low efficiency of the head light. Should it occur for any cause that the battery does not deliver current, the parking lights will fail to operate when the machine is at standstill, but pilot bulb and tail lamp will function regularly, although with less brightness, as they are supplied with current from flywheel magneto.

However it is necessary to provide for the battery maintenance in order to restore parking lights. Magneto / Battery / Parking Lights / Red & Blue Cable

MODIFICATION No. 6) – LAMBRETTA 150 cc. WITH PARKING LIGHTS

The new electrical equipment mounted on the Lambretta 150 cc. includes a cell battery, which permits to utilize lights for parking purpose. Arrangement throughout

The electrical equipment is supplied by means of a flywheel magneto, which induces low tension current to the twin-filament bulb ( 6V-25/25W), incorporated in the headlamp, and 6V-l ,5W bulb in tail light; it provides further for battery charging through a rectifier. The 6V-4Ah battery delivers direct current to the 6V-5W bulb in head lamp, ( acting as pilot and parking light), and 6V-l ,5W bulb, (acting as tail and parking light).

The lighting control consists ( as in the old equipment) of a switch, located on the r. h. handlebar; the switch lever serves as well to earth the engine ( Position « M » on the
switch). The switch is coupled with the horn button, still operated by alternating current. If a speedometer of illuminated type is fitted, the socket should be linked to the terminal plate in the head lamp ( See Wiring Diagram).

For the lighting circuit use only the following devices and bulbs:
Flywheel magneto – 27W-6V
Marelli Make Drwng 12 M 1231
Filso Make Drwng 12 M 1241

Head lamp – Twin-filament bulb 6V-25/25W / Pilot and parking bulb 6V-5W
Tail Light – 6V-l ,5W bulb
Speedometer – 6V-l ,5W bulb
Battery – 6V-4Ah

Either dry batteries ( Pat. Varley-Safa) or lead-acid batteries can be mounted on the machines.
