SEV means Société d’Equipements pour Véhicules automobiles. SEV (France) has no relation to CEV (Italy). SEV combined with Marchal in 1963, and then was bought by Ferodo in 1970. Ferodo bought CIBIE lights, and then became Valeo in 1980.

Solex 62254 early & late
The Solex fuel pump membrane and maybe the plastic seats and balls are needed often to replace deteriorated 30-50 year old ones. It’s easier to replace the entire pump, membrane, and membrane seat, but more costly. When the top cap or post is unscrewed, the top check ball easily falls out and gets lost. Often a not working fuel pump only needs a ball, or a new membrane. The pump check balls can be tested by blowing and sucking through a piece of small rubber hose or fuel line. The lower line only blows and does not suck. The upper line only sucks and does not blow.

Right control with wires loose, with wires taut, and end view.
The 1961-86 Solex right inverted brake lever also controls the throttle. Either squeeze the brake or twist the grip to close the throttle. A cam in the grip pushes that little trigger (center photo) which pulls the throttle wire. The single-ended throttle and brake wires are ordinary “universal” moped inner wires.

Yellow – main power from stator to switch paddle (power for the lighting exits the stator via the serrated stud; there is no wire connection between the serrated stud and the switch. The switch paddle must contact the serrated stud when the switch lever is turned counter-clockwise)
Red – power from headlight switch paddle, through spring and bronze strip, to headlight.
Blue – power from bronze strip to tail light wire
Green – ground (wire from headlight to fuel pump screw)
*Note: the 1966-72 S 3800 USA (and the S 3300) is similar, but instead of a ground wire, there is a ground tab mounted on the front of the fuel pump. The tip of the bulb touches the tab.
