Repairing Broken Battery Wires

Can you teach me how to take out the computer control panel?

And:

Because I need to re-solder the wire that connect to the battery compartment.

Mike here: I've not had to do this so I've checked with our resident hardware expert, Dr. Clay Sherrod:

The control panel circuit board does NOT need to be taken off to
re-solder a broken battery box wire; it can be easily attached to the
two exposed tiny posts on the lower right corner of the control panel
from inside the base, once the base plate is removed; the control panel
does NOT come out....it is glue and press fit into place.  Thus those
two posts are the only method by which the consumer can reattach the
broken wires.  Make sure you have the polarity right....hopefully only
ONE wire is off and that way you know for sure which of the tiny exposed
wire posts to reattach one broken wire.

Thanks to Mike and also Dr. Clay,

But the problem is I already forgot which is positive and which is
negative.

Can someone provide me a photo of this?

I am trying to repair the battery pack in an ETX-90/EC I got at a yard
sale. The positive terminal and the negative terminal of the battery
pack each have a wire attached, but the other ends of the two wires are
disconnected. Does anyone know where these wires should be reattached?
Thank you.

And:

Thank you, Mike. That article provided the clue I needed to solve my
problem.

You mite want to add the attached .jpg pix to the article, together with
these directions:

1. Use insulated stranded wire to connect the NEGATIVE terminal of the
battery pack to the terminal numbered 1 on the circuit board.

2. Connect the POSITIVE terminal of the battery pack to the terminal
numbered 2 on the circuit board.

3. Be careful not to short terminals 1 and 2 together when you solder
the wires on.
