RE:K2>Alignment @Test, Part 1, #6249

   Greetings All,
...Having made it to Page 44, after the initial power
up to initialize the EEPROM (verified by the INFO 201
display), the K2 was turned off and then back on after
a few seconds, and the display only gives me "ELE",
not
"ELECrAFt", as was to be
expected...Furthermore,tapping
the display switch once did not show the supply
voltage
and current, which is from a battery (12.67vdc @
7A.)..
.."ELE" remains in display. Also, the bar graph to the

left of LCD is not illuminated, but should I expect it
to without any signals at this stage of construction?
...It looks like trouble shooting code "060" might be
applicable for "...partial(incomplete)display", which
is not specifically addressed.  The relays do appear
to
activate when K2 is turned on. ANY past problem
solving
tips to help locate the area of the "glitch" will be
greatly appreciated.  I am sure there will be more as
the project progresses.  I read the mail every day, so
anything that helps to get the K2 closer to completion
helps ease the pain of waiting for the third wave K3
distribution...............73, Tim KE5LYT

Tim,

IIRC, that 'ELE' indication is a sign that pin 1 of the front panel 40
pin socket has not been soldered.
Peer under the LCD to see if that condition is present.

If pin 1 is not soldered, it is almost impossible to solder it from the
bottom without removing the LCD (don't try that unless there is no other
choice).  Fortunately, one can solder the socket pin from the to of the
board - it requires that you carve away a small bit of the socket
plastic next to the pin to be soldered so you can get the soldering tip
onto the pin and its solder pad.  Solder can be applied either from the
bottom (snaking the solder under the LCD) or if you removed enough
plastic, you can apply the solder from the top of the board.

If U1 pin 1 is not the problem, be confident that you have an unsoldered
(or poorly soldered connection somewhere on the front panel board, and
your challenge is to find and fix it.

73,
