Wanted to test out my wiring job so I hooked a battery box up to the battery cables just to see what would happen.Head lights work,signals work,horn,fan all seemed fine.Instrument light rheostat fuse blew right away. I also hae no parking lights.>>

The instrument lights and parking lights are on the same fuse. Disconnect the wires at the instrument light rheostat and see whether the fuse still blows. If so, check all the connections at the parking lights. If not, check that none of the R/W wires is grounding out. A less likely problem is a bad instrument light. (I've never seen one.)

<<Wiper motor was running but would not shut off then that fuse blew also.>>

I need to know your chassis number for this (or if your wiper plug comes directly from the front harness or is a separate piece.)
