Don, had something similiar on a 169 several months ago, pull the board out of
the set and
check the 2 traces farthest to the left of the board at the bottom with a
magnifying glass, the
traces break, mine actually had 3 traces broken, had to Ohm out the third one to
find it,
hope this helps, Larry E
