i had a similar problem with my 143-2. the normalizing gates didn't
normalize to env # 1. the blank wire that went through all four
circuit boards appeared ok, but further scrutiny revealed that it had
some "wiggle" to it. it needed to be soldered again, though the wire
itself was not broken at all, just too loose to have a good
connection at the joints.

as soon as i re-melted the solder that was already there it worked
perfectly.
