alternator wont charge

^^Good point Redfish. READ!!!! There has been a NUMBER of "rebuilt" alternators show up right on this board with (incorrect) grounded field terminals or isolated field units (incorrectly called "dual field") being sold for older 69/ earlier applications

CHECK YOUR NEW ALTERNATOR!!! Check continuity to the case with both field terminals. Should be OPEN, or INFINITY

Check field--to--field terminal....Should be a very low resistance.

This is for 70/ later with TWO field terminals
