Wiring Loom Auto Engine Air Cooled Battery, Electric Start

Basic Universal wiring loom for Lambrettas with an Auto engine fitted. Generally Air Cooled Engines. Water cooled motors would need separate Thermostat/Heat Sensor wiring.

Wiring included for a Starter Relay / Electric Start button in the headset area and safety start switch facility ( the front brake lever has to be pulled for the electric start button/key to operate). The necessary switches are available separately.

Lights and Horn 12 Volt AC

Battery charging wires are built in, but the main thick starter motor wires are not, usually they are already attached to the engine. They can be made to measure on request.

Wiring Diagram supplied.

Some other parts that are available:

Electric start button - It can be mounted onto the handle bars or similar position, we have one available separately part number 24 613 5020 in the Autos starter motors section - One 15mm hole will have to be drilled.

You will also require a safety switch that inserts into the clutch outer cable or similar, this makes it not possible to start the engine if the scooter is in gear without first pulling in the clutch or activating the switch. We have this part available separately listed as a front brake light switch in the Vespa Light Switches section.

A Starter Relay - This can be found in the Vespa Light Switches Section.

A Battery Charging Type Voltage Regulator Box. See Vespa or Auto electrical section.

A 12 V Battery. We recommend the CB9-B or similar, this fits correctly in the majority of Vespa battery trays, and has plenty of power to turn over the motor. Please check the battery dimensions in our battery section, against the size of your battery tray.
