1. Tomos Magnetos
2. Service Info
IDM magnetos, made in Italy, are on some early-to-mid-1990’s Tomos. They are CEV-compatible, and have the same appearance.
Iskra magnetos are made in Slovenia (which was part of Yugoslavia before 1991). They are original equipment on most Tomos mopeds from 1989 to 2007. Iskra means “spark” in Slovenian.
AET After about 1993 Iskra magnetos were labeled AET. Iskra electric motors, AET electric equipment and Tomos mopeds were (or are) divisions of Hidria, a family of Slovenian manufacturing companies. Iskra-AET magnetos have the AET logo stamped on the flywheel, and the Iskra name cast into the back side of the stator base plate. So they can be called by either name.
Tomos mopeds, USA models, had many magnetos, but many were interchangeable. The magneto brands Ducati, ZEM, CEV, IDM, and Iskra-AET, each had different versions. They are all listed below, in order of VIN code and year range.

The IDM 6411 magneto has a reputation of being faulty. The CDI ignition looses spark. When that happens, both the CDI-coil unit and the magneto assembly must be replaced.

In 1998 the 230.327 magneto changed to a “4-star” or “plus sign” design. 3 of the 4 coils were for lighting, connected in series, and one coil was for ignition. So the output wires did not change. The base plate screws changed, from three 4 mm, to two 5 mm.
1974-1997 engine cases had only mounts for 3-M4-screw stator plates.
1998-later engine cases had mounts for both 2-M5 and 3-M4-screw base plates.
In 2003 the engine case, on all models, became electric-start-ready. The magneto did not change, but the magneto part number did because a rubber grommet was added.

In 2001-02 the A35 Revival was the first Tomos with electric start. The 230.842 magneto was the same as a 230.327, except it had an extra wire for battery charging, and a large flat gear on top, for electric starting.

for Euro models
Engine cases: You don’t have to know the year or model to know what magneto(s) fit at particular Tomos. You only have to know what left-side engine case it has. The stator plate has to fit the engine case, and the flywheel has to fit the crank.
From 1974 to 1997 there were three M4-0.7 thread stator plate holes, for A3 and early A35. 3 total.
From 1998 to 2002 two M5-0.8 thread stator plate holes were added, for mid A35. 5 total, 3 unused.
From 2003 to 2006 the electric start affected the wires grommet, for late A35. 7 holes total, 5 unused
From 2003 to 2013 two M6-1.0 thread pulser coil holes were added, for A55. 7 holes total, 3 unused.
Flywheels: All the flywheels, both 80 and 90 mm ID, fit the same crank, but they can have different points cams or ignition triggers. Some flywheels do interchange, some might, and some don’t.
