there are four places where the same voltage should be observed while
the car is running:

the alternator output
the battery + terminal
the fusebox
the starter big wire terminal

measure these with the blue wire connected vs. your jumper (where
exactly *are* you getting that "trusted power"?) and see what's up.

troubleshoot your connections (+ and grounds) at all four places, and
that nasty battery wire under the carpet.

dress warmly, bring your meter and some paper and take lots of notes in
case you don't get to the bottom of it.  Start applying fastener
loosener (WD 40 or whatever) to the voltage regulator screws now, since
one of them tends to get weak due to being the ground path for the
regulator current.

Be careful when measuring resistances (between the four places) not to
blow up your meter, best to have the battery ground disconnected while
doing it.
