Re: crack in circuit board

I just learned that our 1989 audi 100 has a hairline crack in the printed
circuit board behind the speedo and tach on the instrument panel.
Has anyone had a similiar problem and how did you solve
it. Is there a special trick to soldering the crack?
Just recently fixed my wife's 1988 90q instrument panel which had this problem.
You can take the panel apart and solder a wire over the crack. (You have to
locate it first.) Just scrape a bit on each side to expose bare copper, use a
soldering iron set to a temperature that doesn't smoke the solder rosen, and
solder a lead (from a spare resistor, say) across the crack. Then cut off the
unwanted part of the resistor. Contact me for more details if you wish. (Next
planned email access is Monday eve.)
