Shock will NOT occur. The charge is held in a sealed capacitor with insulated wires. Its small ( about 1/4" in diameter x 1/2" in length)
It sits on the lens housing and comes off with the flash and sensor board. I have removed several bare handed and nothing.
In order to get a shock you have to touch the bare wire. There are no bare wires past the insulated covers. the only point of shock is covered by a clear plastic cap. any other bare connection you see has to be charged with voltage via the program setting and then the button used to snap off photos. ;-)
That being said....... It is a MAJOR pain in the azz to remove the covers from the lens housing, as well as a MAJOR pain in the azz to remove the boards and covers on top of it.
It is not for the faint of heart. It is a very daunting project if you are not mechanically / electronically inclined.
New used A520's can be had for under $60.00.
I suggest you go that route or buy a newer better model such as the A720 IS.

You may be able to find a Konica toMinolta or Konica to M42 adaptor. Some adaptors are available...some aren't; it depends upon the film plane dist. and mount diameter. For instance you can get a Nikon to Canon adaptor, you can't get a Canon to Nikon adaptor. Email KonicaMinolta and ask them.

The Penta K110D has a 1.5X crop factor so a 17mm lense would be the equivalent to 25.5mm (in 35mm standard), therefore may not give you a 103 angle view. You would not really notice that much difference between 17 and 18mm.

I have a similar problem but haven't found details on what all is involved taking it apart.

You probably have to set the aperture manually on the lens, because it
might not have CPU contacts. I think changing the aperture on the
camera will probably have no effect, so just try twisting the aperture
ring to wide open.
You usually have to set the aperture at the minimum setting (highest
number) so that if the camera is choosing the aperture, it can stop
down to the required value.
No good having it set at f2.8 if the shot needs f11.
If the lens is very old, it might have a manual iris that you have to
set yourself on the lens. The lenses that stop down automatically will
have a tiny peg on the mount that a suitable camera can operate. Gentle
pushing of this peg while looking through the lens will tell if it is
stopping down - set it wide open first.
If you have a depth of field preview button, this will also have the
same effect with the lens on the camera if the body matches up with the
lens.
