Chris ,
Thank you for your reply.

> You should be able to power the PIC with the PICKit3.
I am not sure of that.
If I  connect PICkit3 only to a board with PIC, ( and no external power is =
there),
MPLAB( I am using) does NOT recognise any target device being connected.
( I tested that  with 44 pin demo mainboard by Microchip )
But as soon as I connect the external power to the mainboard, target device=
 is recognignised=20
