How does one go about whether there is a draw through the alternator as opp=
osed to some other path? I.E. Exactly how & at what terminals is this teste=
d? How sensitive of a meter?,=C2=A0 (analog or digital?), amps or resistanc=
e?, etc.Thanks,Gary Hodson

When there is a draw through the alternator, one of the diodes of the recti=
fier is gone. You need to swap the alternator.
