Pulled Cluster Wont Start.

I always mix baking soda and water in a cup and then stick the end of the cable down into it until the blue bubbles quit fizzing up. You can use the cable end to stir the solution up every once in a while. Pour the solution over the top of the battery when you're done, cleaning the terminals and flush the whole thing with fresh water til it's clean. I had a negative battery cable once that looked perfectly good on the outside, but the whole wire was corroded inside where you couldn't see.

Also check the grounds on your steering column that you dropped. There should be a ground wire with a flat washer on both ends that grounds the steering column to the dash frame. Check both ends for tightness.
