1990 Dodge Cummins, 111,000 miles - does not charge, is not putting out.
Installed new Chrysler alternator from NAPA and isolated field electronic regulator. Parts store (NAPA) checked the alt., said it is OK. Cleaned all ground/hot connections. Battery is 12.6 v. Have 12 v power at reg. and alt. Key "on" and both field pins hot (12v).
Any ideas, suggestions? Thanks.
