What was the manufacturer of the old alternator versus the new??
My alternator was a Leece Neville, when it failed I had it rebuilt but I marked all the wires and took pictures so I could reinstall.
You might email Prestolite (who owns Leece Neville) and request the information you are looking for. firstname.lastname@example.org
is who I had emailed for a new alternator model if mine couldn't be repaired.
