Thanks Soren - it may be a while before I have access to the necessary tools, but once I do I will give that a try. > But please note that multiple parts in the power supply circuit > often dies when something like that happens.... and yes, as was stated by a few others that may indeed be the case here, but for the cost of the part and a few minutes time I may as well try!

For a bit of background, the net4801 was acting as a routing computer for a remote wireless network repeater station up on top of a ridge on an island. Due to the remote location the system is powered by solar and wind with a large battery bank. The short occurred not on the soekris or on the lines between it and the battery, but in a line that heads up to the wind generator. The short was a result of storm damage and was not a dead short but an intermittent arcing to ground (via the tower) and never pulled high current long enough to trip the fuse that is in place between the batteries and the equipment.

Actually things look ok in that respect, I took that picture before touching things and after wiping the residue off the board looks ok, while the part seems to have opened up and spewed the nice fan you see there. Thanks for all your responses!
