I have a '88 90 that the dash lights quit working.  I checked the fuse
and it is all right and tried adjusting the brightness.  Has anyone else
had this problem or have any suggestions on what I might check.  Thanks
for any help.

You may have a break in the dash circuit board or in the ground return.  To
determine this you will need to pull the dash and test the connectors using
your Bentley.  If the power and ground are OK, then dash disassembly is
needed.  This is feasible, but time consuming.  Once disassembled, you must
scrutinize the printed wiring circuit to the lamps including the control
reostat.  A multimeter is very helpful for this process.  Breaks in the
traces are very difficult to notice until you have found them with a meter.
