02 7.3 has slop in the shift rod, i thought the little black roller under the dash might help straighten it out... But it killed my dash lights. My dash doesnt do anything now. And now my truck wont start. But batterys are reading just over 12V. Im going to slow down and dig into fuses tomorrow. But im just a little lost that it doesnt even want to start. It acts as if the batterys are dead. Ive checks terminals, connections and my wires under the dash. Just trying to get more ideas.
