Daelim Wiring: Daelim Motor Corp (DMC) made Trac mopeds for the US in the 1980’s. See Trac Wiring.
Dansi Magneto: These 3-wire magnetos are used on Benelli, Morini and Rizzato moped engines. Dansi magnetos are included here in wirings because of the number that is stamped onto the 80mm ID flywheel. That number determines the brake light wiring, brake light switches, and tail/brake light type, and more importantly, whether or not it has a “secret” wire that needs to be grounded. Dansi 101286 (anti-clockwise) and 101441 (clockwise) wires are: red = ignition, black = lights, green = brake light. Dansi 101765 (anti-clockwise) and 101732 (anti-clockwise?) wires are: red = ignition, black = lights, green = ignition ground (brake light). If you have an external ignition ground type 101765 or 101732, always ground the green wire first, when checking for spark. See Morini Wiring.
Demm Wiring: Demm Smily, US models 1976-78 have Demm one-speed engines with CEV 6933 magnetos. The blue magneto wire is an ignition ground that also powers the brake light.
Derbi Wiring: Derbi mopeds, US models 1976-1989, except the DS50, have Motoplat 3-wire magnetos with points, and an external ignition ground on the blue wire powering the brake light. Inside the tail/brake light is a secret hidden ignition ground resistor. If that goes bad, or the wire leading to it, the ignition will loose spark when the brakes are applied. If any of the brake switch wires are also disconnected, then there will no spark all the time. The front ignition ground junction is on the right headlight mount, which is floating in rubber. The rear ignition ground is on the left rear fender bolt, underneath. Both of those places get corroded or loose. Ground the blue wire from the engine first, when checking for spark. Then all those rusty loose grounds don’t matter. That disables the brake light, for emergency or troubleshooting.
Derbi DS50 main switch (ignition) has 20mm mount hole
