in my 1980 olds cutlass calais the gauges are not working,took them out tested them they work fine the fuse is good but no power to the gauges or dash lights. i need a diagram for the dash power feed i am thinking a bad wire behind the fuse box. i had a short in the engine compartment that fried the fusable links which i changed. it will start and run and charge but no radio,headlights,wipers,or tail lights it has me scratching my head. i was going to replace the headlight switch and wiper switch unless i can figure out the power leads and apply 12v to it to see if that works.
