The Magneti Marelli Dinoplex was one of the first commercially available automotive 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
(the first Ferrari with an electronic ignition) and 246, Ferrari Daytona, the Fiat Dino Coupe and Spider (the
first production cars fitted with a Dinoplex ignition), Lancia Stratos and the Lamborghini Countach. This is a non-commercial website which aims to provide helpful documents and information on how to diagnose problems, repair, restore and install historic ignition units made by Magneti Marelli. Use of the included documents and information is at your own risk. Working on ignition systems requires good electrical knowledge and application of the required security precautions. You are free to use all material to repair and restore ignitions in a commercial environment but please contact me first if you plan reprinting, hosting or publication of any material. |

Magneti Marelli Dinoplex C AEC 101 C/D/E
(1968-1971) Variations: AEC 101 C: Early type, first PCB version, metal switch, long wires with color coded plastic rings AEC 101 CA: Metal Switch, long wires with color coded plastic rings AEC 101 CB: Early types had a metal switch, later types bakelite switches, long wires with color coded plastic rings AEC 101 D: Metal switch, short wires with white plastic rings AEC 101 DA: Bakelite switch, short wires with white plastic rings AEC 101 DAX: Bakelite switch, short wires with white plastic rings AEC 101 E/EA: Short wires with a three terminal AMP connector, 12 cylinder engines (one unit per bank) Coil: Magneti Marelli BZR 205A (3 terminals) Replacement Coils: BZR 205A: Magneti Marelli BAE202B Cars with a factory installed Dinoplex: AEC 101 C: Early Fiat Dino 2.0l Coupe (from #02466 on) and Spider (from #0833 on), Abarth 2000 Sport Spider, Abarth 1300 AEC 101 CA/CB: Later Fiat Dino 2.0l Coupe and Spider, early Fiat Dino 2.4l Coupe and Spider AEC 101 D: Ferrari Dino 206 GT AEC 101 DA: Ferrari Dino 246 GT L Series AEC 101 DAX: Early Ferrari Dino 246 GT M Series, Ferrari Daytona GTB/4 Coupe US (two units) AEC 101 E/EA: Ferrari Daytona GTB/4 Coupe US (two units), Ferrari 365 GTC/4 US (two units), Ferrari 365 GT 2+2 US (two units) Documents: • Dinoplex C AEC 101 Diagnose and Repair • Dinoplex C AEC 101 C/D/E Component and PCB Diagram (PDF) • Dinoplex C AEC 101 C/D/E External Wiring (PDF) • Dinoplex C AEC 101 C/D/E Replacement Parts (PDF) • Dinoplex C AEC 101 Transformer Datasheet (PDF) Circuit Diagrams: • Dinoplex C AEC 101 C (early type) Circuit Diagram (PDF) • Dinoplex C AEC 101 C/D/E Circuit Diagram (PDF) • Dinoplex C AEC 101 C/D/E Circuit Diagram in Color (PDF) Car specific wiring diagrams: • Ferrari Dino 206 Wiring, '68 Europe (PDF) • Ferrari Dino 246 L and early M Wiring, '69 Europe (PDF) Dinoplex C "C", "D" and early "CA" models were fitted with a metal housing for the Normale/Emergenza switch, later "CA", "CB", "DA" and "DAX" models came with a bakelite switch housing. The Normale/Emergenza switch selected between the capacitive Dino ignition (Normale) and a fallback Points and Coil ignition setup (Emergenza) in case the Dinoplex should fail. In most setups the tach was only functional in the Normale setting and disabled in the Emergenza mode. Dinoplex C "E" and "EA" models were supplied without switch and Emergenza/Normale wiring, also there are no screw holes on the side for the two wire clips as in the "C" and "D" models. ^top |

Only a small batch of units were produced, this type and the 101 DAX are the rarest model of the Dinoplex C series. Components and PCB were an early, simpler version of the later Dinoplex C. The enclosure is equivalent to the very first C type ignitions, except that it has no switch and three short wires with a three terminal AMP/TYCO male connector. Some AEC 102 units had the electronics 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 natural silver. Original units can be identified by the stamped type description and the correct text and serial number application. ^top |

Another batch was produced in 1978. This batch can be identified by the enclosure cast, which has no serial number and the cast is a bit more rough than the original batch. The AEC103BA type featured two connectors to easily switch between the Normale and Emergenza (Fallback) mode. All AEC103 units are potted in epoxy, making a repair very difficult. ^top |

Magneti Marelli AEC 106 Raceplex "Ignition Sistem For Racing

This ignition was also used as replacement for the Dinoplex AEC102, such as in the Alfa Romeo T33/3. The circuit board is an early version of the AEC104B ignition, Marelli apparently tested their new ignition in race cars this way before they launched it as a commercial product. The ignition accepts trigger input via points or a magnetic pickup in the distributor, depending on the version. With a magnetic pickup the spark triggers on the rising edge as soon as the signal level reaches ~1V. This is the first Dinoplex ignition featuring a rev limiter. The limiter was installed as piggyback module on the main ignition module, this setup was also used for the AEC104B-660 and AEC104B-780 later on. Early versions are painted black and can be identified by the single Marelli "Ignition Sistem for Racing Car" logo
label in yellow, later versions also had a red aluminium type label with the type code and serial number, as well as a round warning
sticker labeled "90º C - MAX - 194º F. The rev limiter had its own Magneti
Marelli label, which was silver in earlier versiond and yellow in later ones. Last versions made featured a blue Magneti Marelli label similar to the one used on the
AEC104BK. |

All setups with a magnetic pickup trigger the spark on the rising edge as soon as the signal level reaches ~1V. The B-660 and B-780 types also featured a rev limiter which was mounted on top of the Dinoplex base unit next to the resistor module. All AEC104 ignitions are potted in PU and epoxy. ^top |
