No fuel gauge, no temp gauge, no battery warning light on dash?

My old 1987 cavalier estate car was broken into the other night, the barrel was broken and lots of wires cut, car now starts and all wires and fuses replaced and repaired.The bottom right bit of my dash doesnt work now and the car isnt charging. Is it just a loose earth somewhere and something simple I cant find..Going to buy a haynes manual..
