Yes, you are in the same place we are. We get bad units that have a good
diode, pull the diode and see a number on it, but it does not trace to anything
and there is not technical info on the unit. If we could at least
trace the numbers
to some source it would help. Also running the diode into that flat area usually
will damage the mirrors, that is what I have found out, once the mirrors take
a whack it is down hill from there.
