Most often, for me, this has been when the brushes are
worn. Perhaps you can pull the brushes from the ALT
and measure how far they extend. Check it against
Bentley, Haynes, or have someone (me) look it up for you.
The brushes can be readily replaced. I buy them from
an altenator and starter motor rebuilder, and pay the
outrageous price of $1 each. ($5 for a set of starter
There were two ways I saw glow on my A2s. First when the
load was high, and RPMs were low. This was usually
brushes. The second was when the load was light, and it
was dark. Then there was sometimes a glow until more load
was put on the electrical system. I never figured this out
but several cars had it.

Belt tension could be a factor as well, if the belt is
slipping. My assumption is that you have the belt problem
Personally, I've never broken any bolts on brackets. But I
have seen quite a few friends cars with them broken. The only
explaination is that someone moosed it on at some point, or
they tried to compensate for not having all the fasteners.
My experience with brackets and adjustments, is visit your
dealer and get all the hardware you need to make it right.
If the brackets aren't working right, it will be a continuing
problem. It doesn't hurt to lube or neverseeze the adjuster
threads, if you have those. (I think your car is too old for

I think you may have had the prior owner substitute another filter.
In the 80's, several owners around here got GM filters because they
were readily available at parts counters. Just a guess.
Many owners had significant problems with high parafin content
and high water content, as many gas stations trying to play the
diesel game failed to properly handle diesel fuel. Particularly
when the WX was cold. I even had one try to thin it with
gasoline when we had several days of below zero (F) days.
