Dano, head of the Scooterlounge IT team, was having some problems with his lights on his SX 200. So we decided to have a little evening session to get them sorted out. The SX is totally stock, with the exception of electronic ignition. So we worked, like any good detective, going through the electrics methodically, part by part. First we checked that there was power from the stator. Yes. Then we checked for power to the loom. Yes. Then we moved up to the headset, and checked the connections up there. Ultimately, we found a bad ground in the wiring junction at the headlight. That is a common source of lighting problems. Problem solved.
One thing I wanted to highlight was Dano's regulator. Dano had Lambretta expert dial in his scooter, Derek in San Jose. Derek modified an old Lambretta regulator/rectifier box so that it could discretely hide a small regulator. He cut the bakelite internals and discarded the old electrical items. Using the old connectors at the top, he soldered in the needed connections for the regulator to the loom. When the cover is on, you can't tell that it is anything but stock. Very very nicely done!
