RE: BOSTON QUATTRO CONTROL HERE!

Before you strip out the alternator you may want to check the
contact brushes in the alternator. They remove from the back of the
alternator with two screws. In my experience two things generally
happen, One of the spring loaded contacts is stuck in place and not
making contact in which case a little WD40 will return the spring
force and you can replace the brush assembly and keep driving. Or the
brushes are worn to the point where they don't contact the armature.
A new set of contact brushes is probably 1/10 the price of a rebuilt
Bosch alternator. I have sent two Audi's to the junkyard with over
200,000 miles on them with the original alternators and their fifth or
sixth set of contact brushes. I did however replace an alternator on
my current '87 5000Q last year. My understanding is that the voltage
requlator circuitry is built into the alternator and this failed.
When this happened the alternator produced no voltage whereas worn
brushes will generaly(but not always) produce some voltage. I got a
rebuilt Bosch unit from Import Auto Parts in Worcester for arround
$200. They also sell Lucas units for about $50 less but as an owner
of a Triumph motorcycle with Lucas electricals I opted for the Bosch.
