Electrical problem
1994 Chevy S-10 4 cyl Two Wheel Drive Manual

94 s-10 2.2L. There is a short somewhere and when you turn the key over the engine light clicks and flickers and all accessories, headlights, radio won't work at all, but, you can turn the steering wheel left or right and the short goes away, and when I try to start the truck, the black wire from the steering harness (under the steering column), which grounds itself, catches fire and melts. Thank you.
