[GreenKeys] Slow Release Relay in LESU? Whaffo?

[Nick England]

Thanks. Good idea.  I’ll see if I can find a wiring diagram for a LESU that
includes one and figure out how it is wired.
Maybe after I get this ASR finished. I still need to de-mouse the typing
unit and dome reperf, check out all the wiring, and re-lube it all.
It is a fun project.
