Hi -

I'm getting outfitted for K2 # 5422.  Holy moly -
so far I bent a lead over soldering in control
board's U10, and dropped the LCD display onto a
tile floor, cracking the seam.   What's a fella
to do?  Parts guys are coming to my rescue.

I secured a auto-ranging Digital MM and a ESD static
pad and wrist strap - to further help in this "kit"
journey!  Solder sucker and brad and mag lamp - are
somewhere in UPS's system.

Question:  I'm measuring resistances on Control Board,
ala page 21 table.  On a few measurements, I'm getting
MUCH higher resistances than table indicates:

  U6 pin 13  supposed to be > 100k   got INFINITE
  U6 pin 14  supposed to be > 100k   got INFINITE
  U6 pin 29 & 30      to be > 70k    got 85k
  U8 pin 2            to be > 100k   got 6.6meg
  U8 pin 15 & 16      to be > 100k   got INFINITE

Do these readings sound reasonable?

Thanks, 73's
....coming to the next bend in the river, see
a dock up ahead.  :)
