Electrical problem with Timecutter 42"

Hello All.
My Toro  74360 serial 290011235 mower has a weird problem. I hugged a tree a little close on the left side at the rear wheel  and the mower instantly died. After a couple of tries to restart it turned out the main 30 amp fuse was blown. After replacing it the mower would start and run but as soon as I try to put on the blades or move the levers off the resting position the mower dies. I need to know the wiring to be able to figure out what is happening. If anyone has heard of this i would love to know what it is, or if anyone has a wiring diagram for my particular mower that would be great. Thanks!
