Default 77 vette instrument cluster electrical prob

Hey guys please help
"Here we go"

I am currently installing led lights in the cluster (did that) the lights dont go on. Me moving the cluster around something had sparked (dont know what it was) now my gauges are barely working. the only gauge that works fine is the engine temperature gauge. volt ,oil pressure gauge barely moves, the clock never worked. Before only one light worked "GEN" was working, now only 2 lights work gen,low fuel light, please help tanxxx

P.S. speedometer & tachometer works fine

Do you have a wiring diagram and understand how to read one and apply what you see???

Do you have a volt/ohm meter???

I have a volt meter & very good mechanic friend (better than me) that helps me out this is my first classic car. Today I checked the back of the cluster, the printed circuit is crappy (peeling ,edge curling) at best maybe I should start there before buying new gauges ??
