Quick charging question...
I did this conversion.
PRE-1970 CHARGING SYSTEM CONVERSION TO TRANSISTOR VOLTAGE REGULATOR
There are a number of reasons one might want to upgrade a pre-1970 system to a post- 1970 transistorized voltage regulator. The list of reason include
•Chrysler recommends you switch to a transistorized voltage regulator if you upgrade to an electronic ignition from a points style ignition.
•If you have to buy a new voltage regulator, the difference in cost is only about $5-10 more for the transistorized unit. Not to mention, the quality of replacement early style voltage regulators is spotty.
•The transistorized voltage regulator will have a longer life.
Diagram #3 below describes how to install a 70 and later voltage regulator on a pre-1970 Mopar.
Diagram #3
Basically, a wire is added to the second field brush on the alternator. On the original alternator, this brush is grounded to the case of the alternator, so you'll need to change the alternator to a 1970 or newer style. The second field wire is connected to the outside plug on the newer voltage regulator (two plugs, one is in the middle, one is on the outside). The original field wire that ran to the "FLD" plug on the original voltage regulator (green wire) needs to be connected with the wire that ran to the "IGN" side of the original voltage regulator. This wire (both the old FLD and the old IGN) need to be connected to the center plug on the newer voltage regulator as well. One more important step is required, the new voltage regulator must have a good case ground (-) to its mounting surface. If there isn't a good ground to the new voltage regulator case, the charging system will not work.
