    The problem seems to be a charging issue

    This a gen1 ? The bullet Diag wires you are looking for are under the rear r/h side near the mesh on a gen1.

    If it's a charging issue you need to measure the input from the stator into the reg/rec

    They should all be pretty much the same output at tickover and almost identical again at 4K rpm also. Measure all three across one another with a multimeter. If one is different or all different the you stator is burning out. Also check input into battery in case the reg is faulty.
