Never mind that it shows a V-8, the charging circuits are the same.

Hi Steven,
Thanks for the wiring diagram, Original alternator was tested twice and showed not charging and needed to be replaced. Replaced with new remanufactured alternator from Rock Auto Parts and new voltage regulator as a precaution had remanufactured alternator tested and it is in working order. Battery has been well maintained and I ensured that it was fully charged after installing the new alternator. On a side note I see that you live in Simi Valley. I live in the San Fernando Valley. With respect to photos I will need to take some and upload.
