After looking over all of our 393 and 292 motors, I think I’ve worked out the pattern for the earlier date codes (our earliest being 04A10, presumably from April of 2010). However an official word on these would be nice as I can’t make sense of the new ones or the letter in the middle (revision?)
In addition, some word on the first production runs of 2-wire motors would be much appreciated. Were there problems with them? I seem to recall something to that effect and ours seem to be much weaker than they ought to be, overheating at minimal or no load with no obvious signs of failure. We will be replacing all of them before Worlds but would like to know if we should trash our parts stock or look for the problem elsewhere.
Thanks in advance!
