I would check for frayed, cut or exposed wires in the dash between your fuse and the sled connectors.
There could be a short there. Things can get pretty crammed up in there and with constant vibrations and jerks going on, wires can get rubbed against sharp edges and wear away their insulation.

No use in correcting the problem if it is to happen again once you slide the player back in the sled.

-Edit- I saw the post on the spring after the fact. So I guess nevermind.
