Bose System Power Relay Location

[Carol, Dave, and Zach Weiss]

Ingo,

 

Good detective work.  I don't see anything like that in the diagram.
You've got the right idea-when it comes to wiring, the diagram is a good
place to start.

Dave,

 

No need.  Yes, I'd found it in the meantime and found something else
that is interesting (thanks for pointing out where it is in the manual,
Dave).  After removing the relay and hooking up the voltmeter, it would
still show 11.5+ volts (even with battery disconnected).  So I knew
there had to be a capacitor somewhere -- and there is (was):  The free
area of the Distribution adaptors at the bottom of the footwell
auxiliary relay housing.  No mention in ETKA of the part number (not
known), but it's a choke (PN# 443 903 547 A) with attached capacitor
that is attached to a red three-prong plug and has three wires going to
it:  Red w/orange stripe, red w/ black stripe and brown.  If I plugged
in a Bose speaker amp, it would drain the capacitor.  If not, the
capacitor would hold it's charge.  As to whether the capacitor is used
for anything else, I don't know.  If I'm reading the unit correctly,
it's rated at 12 A (max 20 A / 2min).  Wonder if it's also use din the
200...

See Bentley for the 200 on page 91.23  It talks about Speaker Relay,
J225

with a drawing that shows (apparently) the general area this Relay
should be

(at least for the 200).  Besides the thorough wire wrapping job,
everything

is tucked in soo close  I feel I really have to tear apart much of the
sound

deadening material, unscrew numerous brackets, etc.

This appears to be entirely skipped in the V8 Audi shop manual (at least
the

1990 version).

Speaker Relay J225 is 19 on Auxiliary Relay Box II, red relay socket.
See manual page 97-60-2.  Aux relays (right footwell) are shown on page
97-40-1.  This relay is also listed on Service Pub. 89-1 V-8 Main Wiring
Diagram, page 2 of 82 (was in my bound manual).  The relay is on current
tracks 753 and 754.  I haven't gone down to the garage to verify the
manual, though.
