Dinoplex AEC 101 Dinoplex AEC 102 Dinoplex AEC 103 Dinoplex AEC 104 Marelli S125 Alternative Ignitions Miscellaneous Imprint	The Magneti Marelli Dinoplex was one of the first commercially available capacitive ignition systems on the market and was quite ahead of its time. The Dinoplex C electronic capacitive discharge ignition was developed by Magneti Marelli in 1967 for Ferrari race cars, development continued in 1968 for the high revving Dino V6 engine (hence the name Dinoplex). Dinoplex units have been installed in a range of racing and performance street cars from the late sixties to the mid eighties, including the Ferrari 312, Ferrari Dino 206 and 246, Ferrari Daytona, the Fiat Dino Coupe and Spider, Lancia Stratos and the Lamborghini Countach and LM002. This site aims to provide helpful documents and information on how to diagnose problems, repair, restore and install Dinoplex units. Use of the included documents and information is at your own risk. Working on high capacity ignition systems requires good electrical knowledge and application of the required security precautions. Please note that documents and site contents are not for commercial use or sale without the written consent of the author. All links marked in grey will be added as soon as possible.

Cars: Ferrari 312 (1967), Ferrari 312 B2, Ferrari Dino 246 Tasman, Ferrari 512 S, Ferrari 512 M, Abarth 3000 Prototipo, Alfa Romeo 33 TT 12 The first Dinoplex ignition unit build, Series A and AA were installed in Ferrari factory race cars. Only a small batch of units were produced, this is the rarest model of all Dinoplex ignitions. The enclosure is equivalent to the very first C type ignitions, except that it has no switch and three short wires with a spade connector each. Early AEC 102 units were potted in epoxy. The type description was stamped into the casted enclosure, unlike Dinoplex C units where the type description was part of the cast and is embossed. The first two series were painted in yellow, the last series was painted in silver. Original units can be identified by the stamped type description and the correct text and serial number application on top of the enclosure. If you want to purchase one and are in doubt, you can mail me photos of the unit for identification. If you have photos or additional infos about this unit or additional cars where this Dinoplex type was factory installed, please contact me. ^top

	Magneti Marelli Distributor S125 Cars: Dino V6 based cars with a Magneti Marelli AEC 101 or AEC 103 ignition Variations: S 125 AX - 15° (1967-1968): 3 cams, two sets of contacts, Ferrari Dino 206 GT, Fiat Dino 2.0 Spider and Coupe S 125 BX - 15° (1968-1972): 3 cams, two sets of contacts, Ferrari Dino 246 GT, Fiat Dino 2.0/2.4 Spider and Coupe S 125 C (1972-1975): 6 cams, two sets of contacts, Ferrari Dino 246 GT/GTS, Fiat Dino 2.4 Spider and Coupe, Lancia Stratos The Magneti Marelli S125 was the default distributor for the Dino 2.0l/2.4 V6 engine, the 15° addendum to the type number denotes the maximum cam shaft advance. S125 AX type distributors were installed in early Fiat Dinos, even before the Dinoplex was introduced. S125 BX are the most common type of all S125 distributors. The later S125 C also featured a 15° maximum advance, but this was no longer mentioned on the type label. For the points based emergency mode in a Dinoplex AEC101/AEC103 setup, a 0,25uF capacitor was installed on the S125 body and wire to the points. The Dinoplex ignition itself does not require a capacitor wired to the points. The original capacitor supplied by Magneti Marelli came in a metal enclosure which was labeled with the Magneti Marelli logo, a production code (as example CE29T or ES29S) and the values 0,25uF and 500 Volt. S125 AX and BX type distributors have a three lobe cam with two adjacent set of points wired in parallel to reduce point scatter and enhance dwell at high RPMs. S125 C type distributors have a six lobe cam and feature two independent sets of points for emission control equipped cars. In the emission control setup, the first set of points (R1) was always active, and the second set of points (R2) could be added by switching ground to R2 via a microswitch installed on the left Weber carburettor when no throttle was applied. As a result this setup retarded the idle advance by 5.5° (camshaft) for better combustion and cleaner exhaust gases. S125 C distributors have the same body as S125 BX distributors but are easily identified by the second hole for the additional R2 contact terminal on the left of the distributor body. ^top
