| Chrysler first introduced their "new"
aluminum lightweight alternators with the 1962 model year. From 1962-69, the
alternator was part of a charging system which used a mechanical type of
voltage regulator (the small rectangular style.) This regulator used
mechanical points (similar to the points on a distributor,) which would open
and close to help regulate the charging system voltage. This system uses one
field wire (usually green in color) and is often called a "single field"
system. The type of alternator used with this system can be easily
identified by looking at the back. Shown above on the left, it is often
referred to as a "roundback" style. The spade for the field wire can be seen
at the 12 o'clock position with the letters "FLD" below it. We offer these
alternators below in both single and dual pulley configurations. It is
possible to use the dual pulley for the single pulley application, however
the second pulley (closest to the radiator) will go unused. Usually non A/C
cars will use the single pulley while A/C cars will use the dual pulley. In 1970, Chrysler changed to an electronically regulated charging system. This system can be easily identified by the flat, square voltage regulator with a triangular plug on it. This is a much better, more reliable system that will keep the battery voltage more stable and is highly recommended for electronic ignition setups and aftermarket stereos/electronics, etc. This system uses two field wires and is often called a "double field" system. The type of alternator used with this system can be easily identified by looking at the back. Shown above on the right, it is often referred to as a "squareback" style. The spades for the field wires can be seen at the 2 o'clock and the 4 o'clock positions with the letters "FLD" next to them. Either wire can be hooked up to either field terminal, it makes no difference. Dual field alternators can also be used for single field applications if necessary by grounding one of the field wires. This will, in effect, turn the alternator into a single field unit. We offer these alternators below in both single and dual pulley configurations. It is possible to use the dual pulley for the single pulley application, however the second pulley (closest to the radiator) will go unused. Usually non A/C cars will use the single pulley while A/C cars will use the dual pulley. If you have the pre 1970 mechanical charging system and are not overly concerned with details of originality, we recommend converting to the newer electronic system. |
