What about a Toyota ;-)

I kinda recall from when I helped at my friends workshop that it�s the other
way around though, the blue wire ( from charging light ) should tell the
relay that there isn�t enough power in the system thereby trigger the system
to start working
I�m not 100 % sure about this though, maybe someone else out there know this
better ....

Anyway, you wrote that you've changed the alternator and I guess you have
the standard item with buildt in relay ??
Then that should be new too - right ??
And with the D+ wire OK,  the only thing I could think of that might spook
things like this is ground wires on either alternator, relay, engine or
gearbox......
or instrument cluster or battery or.....

If it would have been the same alternator it might have been a diode with
weak soldering too but since that�s changed I�d start with ground checks -
all over
