Identifying Chrysler Alternators (1960-1976)
My compliments on an informative post
AMP RATINGS...........the problem here is these girls are OLD and likely have been REBUILT. Once a factory OEM item goest through a rebuilder "it's anybody's guess"
BRUSHES.......BE CAREFUL I've seen cases that "appeared OEM" than had both a spot for a grounded AND an isolated brush, AKA positions for THREE brush holders. Worse, some rebuilders DRILL a spot for a modified, isolated brush holder to convert a grounded brush unit to an isolated unit. AND THE PROBLEM with all this is that sometimes a grounded brush accidently gets installed along with an isolated brush........hooking one of these up can result in either massive overcharge or a burned up harness
The final nail in the "grounded brush" coffin (may have been mentioned) is MISSING OR BROKEN hardware / insulators on isolated brushes which cause them to ground
Unknown casting with evidently factory positions for both grounded and isolated brushes
