Myron's Mopeds

ELECTRICAL PARTS:

Most European made mopeds from about 1970 – 2000 have high quality CEV electrical components, made in Italy. CEV is a trade mark, owned by Fratelli Pagani, that stands for Costruzioni Elettromeccaniche Venegonesi. CEV is now owned by Zadi, a maker of moped fork locks.

All European mopeds, USA models, 1970's and later, had CEV switches, except Puch, Motobecane, and Jawa.

Bulbs are specified by their style, size, voltage, and wattage. #1,#2,#3 are bayonette style 15mm, BA15s and BA15d, where you push it in first a little, then turn it clockwise 45 degrees to go on, or counterclockwise to take off. A single filament bayonette bulb can go two ways, but a double filament only goes in one way. That’s because one prong is higher than the other on a dual filament. That’s so you can’t reverse the tail and brake lights. The BA20d hi/lo headlites are the same way. The smaller bayonettes are #4, 9mm BA9S, and #6, 7mm BA7S. #5 is a festoon style bulb that looks like a glass fuse but it’s not. It’s a high beam indicator lite.

#7 and #12 are sealed beam 4 1/2″ round headlites, where the bulb is sealed inside the glass reflector and lens. Sealed beam bulbs cost much more than replaceable ones so it’s practical to upgrade to a replaceable bulb whenever possible. When your burned out sealed beam headlite is made out of metal, on the back, not glass, then Myrons Mopeds can recycle it, for $22 plus $8 parts plus shipping. Many vintage Japanese and European small motorcycles and mopeds have hard to get sealed beam bulbs, such as CEV171 or 172, with metal backs. A hole is cut and a universal bulb socket snaps in. The original wire plug(s) are re-used. The bulb is a single filament, easy to get at convienience stores, #1156. If the original had hi/lo beam, then it will have just low after the upgrade.

Mopeds frequently burn out bulbs, from both vibration and surges of electricity. Because there’s no battery, the voltage varies a little. At idle the lights are very dim, but at full speed they’re bright. Hopefully they’re not brite white, as that means it might burn out soon. Yellow is good but orange is too dim. For some reason, most old 6 volt mopeds need 12 volt bulbs, or else they burn out. Some bikes need a 12V AC voltage regulator ($45) added on in addition to 12V bulbs, to help prevent bulb burn out. Only when 12V bulbs are too dim should 6V ones be used, with the following exception. The 77-later Puch needs a 6V 21W #1129 instead of a 12V 21W #1156, in order for the tail lite to be bright. Other bikes have issues where the brake light is needed for the ignition to function. Some tailights have a secret hidden resistor inside, that allows the bike to run even with a burned out or missing brake light bulb. See service section for more info about wierd light behavior and what mopeds need what lights to run, if any.
