![]() Ferrari used batteries from several different manufacturers. Most of the serious restorers use reproduction batteries designed to look like the original “Tar Top” ones. 4″圆″ reproduction manufacturer’s logos for batteries. The battery company people cannot relate to Ferrari models and will be looking for this information. When you call for a reproduction battery you will need to know all of the dimensions, the positive and negative post layout and which side you want to use for the logo. The reproduction batteries usually have a 4″圆″ smooth panel, on the long side, for the manufacturer’s logo. The batteries are listed along with most of the major electrical components. If the build sheet information is not available I suggest that you look in Keith Bluemel’s wonderful book Original Ferrari V 12, 1965-1973. The correct battery for a particular car can be found on page four on the cars that have “build sheets”. Used on a lot of the older cars over the years. Oval Foil Magneti Marelli Coil Sticker.Ģ0-1 | Magneti Marelli battery sticker $15.00 The records of the timing of these changes are sketchy at best so the restorers and judges are always looking for original components and photos to try to document the timing of the changes. The changes in pieces like these, which were supplied by outside vendors, normally did not coincide exactly with Ferrari model or yearly changes. Both of these coils used a truncated oval Magneti Marelli foil sticker located 1/4″ from the bottom of the can on the “front” surface centered in line with the resister. The square resisters had the ohm rating silk-screened on the top surface. The coils with the square resisters had a separate mounting bracket with the bracket, pinch bolt and nut, and mounting screws plated with silver or white cadmium. ![]() I believe that both the cans and the square resisters were painted the same color however, over time the resister color might change a bit due to heat build-up. These coils were painted red along with the ceramic resisters. The second series used a square-shaped ceramic resister. The can, bracket and the resister were painted red. These were used as late as the early 250 GTEs. The earlier version used a small tubular-shaped resister that resembled the American “Tootsie Roll” candy, hence the nickname “Tootsie Roll” coils. ![]() At about the same time Magneti Marelli supplied a new series of red coils. These engines had the spark plugs moved from the center of the engines to the lower side of the heads near the exhaust ports. In 1959 Ferrari began production of the new 250 series “outside plug” engines. ![]()
