Like RedFish said, first check to see that you're getting juice to both sides of the dash lights fuse. If not, the problem is between the light switch and the fuse. If you get juice to the fuse, the problem is between there and the circuit board on the back of the cluster. You may end up having to pull the cluster to check the cannon plug and circuit board connections better. What's the story on the spliced ammeter wires? Looks like smaller gauge wire has been installed. Not a good idea if true. Under a load, those wires could overheat and melt the insulation off the conductors causing a fire. If the reason for the slice is that the original wires melted together and were bypassed, that may be your dash light problem....you may have a short or open somewhere.
