If the voltage isn't correct (e.g. 4.8-5.2V) at that point (but

umm.. i think you lost me,.... yes yes this place is familiar it
is "lost land"

as in i am lost i hope there is another way to do this as it
sounds like i can cause more problems trying to find the problems
?

if there is no other ways then i will just have to learn but the
experience level of this diagnostic is really stretching my
noodle(s)

thanks for the help i am sure it is very useful advice and i just
need to understand it.
