Is it not charging at all or just not charging enough?
Had an 18 month old recon one fail with what must have been a short in the
exciter coils It was drawing 280mA as opposed to the <150mA-ish that it was
supposed to through the blue wire. It was charging, but not enough to keep
up with the drain of the AC, rad fan and monster, monster headlamps.......
New voltage reg made no difference. I now have a spare for the Golf2
Have had new stuff not respect the "excellence comes as standard" rule and
fail out of the box, but that was more Lucas than Bosch. Nothing is
I assume that you have checked or replaced the blue wire to the connector on
the chassis rail by the water bottle?
Also i once managed to install a voltage reg on the 200 using the wrong set
of threaded holes on the back of the alternator meaning that the brushes too
far away from the slip rings... Moral: use a good flashlight if you are
doing it with the car on its wheels in the dark........

Subject: intermittent charge issue
Folks, I'm experiencing an intermittent charge with a newly installed Al179x
alternator. (Bosch remanufactured)
Primarily after some time on the highway - and then after "cooling off" for
a while (on the side of the road, or rest area) it works for some time -
though that seems to be getting more variable.
Swapping the voltage reg. had no change, and I confirmed that there was no
charging after the warning light came on.
Anyone ever have a faulty "new" alternator?
Could it be something else? I'm relatively confident it is not an
intermittent igniter circuit.
