The 275s used a new red-colored voltage regulator, still from Magneti Marelli. This is a small 15x40mm foil sticker placed on the short side of the regulator as shown in the photo. It is identified as Tipo RTT 101C. Foil I.D. Tag for Red Tipo RTT 101C Magneti Marelli Voltage regulator.
With the electric fuel pumps there is a fuel filter also made by F.I.S.P.A. The filter element is contained in a steel bowl which is painted gray or an industrial green color which has a decal telling the mechanic to be sure to change the filter. These filters are always packed with mud and rust on the old cars. Be sure that the tank is near empty before removing the filter bowl. Yello F.I.S.P.A decal (FISPA letters clear in a yellow block)
Most of the serious restorers use reproduction batteries designed to look like the original “Tar Top” ones. Ferrari used batteries from several different manufacturers. The correct battery for a particular car can be found on page four on the cars that have “build sheets”. 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 batteries are listed along with most of the major electrical components. The reproduction batteries usually have a 4″x6″ smooth panel, on the long side, for the manufacturer’s logo. 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. A sketch helps. The battery company people cannot relate to Ferrari models and will be looking for this information. 4″x6″ reproduction manufacturer’s logos for batteries. SAFA 6SR3..used on the 410 Super Americas
The rectangular foil coil stickers were used on the late 250 GTEs and Lussos from 1963 on through the 275s, 330s, 365 single-cam cars and even the early Daytonas and c4s. The stickers were positioned 1/4″ from the bottom of the can in line with the center of the resisters. I have seen rectangular stickers that looked like they were printed on gold foil. These may have been an earlier reproduction, or may have been discolored due to the oily vapors and engine heat or may have been originals. Rectangular Magneti Marelli coil Stickers.
