I HAD THE SAME PROBLEM BATTERY DRAIN JUST UNHOOK
THE NEG CABLEPUT TEST LIGHT INBETWEEN POST AND CABLE IF TEST LIGHT IS LIT START UNPLUGING FUSES
ONE AT A TIME TILL THE LIGHT GOES OUT MINE WAS THE CHEAP VOLTAGE REG I GOT AT AUTO ZONE
UNPLUG THE ALT TWO WIRE PLUG TOO AND UNPLUG VOLTAGE REG ANY CHECK FOR SLOPPY KEY

AS FOR THE DASH LIGHTS REMOVE THE DASH PANEL
AND RIG UP TEST WIRE AND MOVE SOCKETS TILL THEY
LIGHT AND PUT A SMALL AMOUNT OF SILICONE NEXT TO EACH LAMP SOCKET TO KEEP IT FROM MOVING
WORKED FOR ME

THANKS BILL
