I have an 86 conv. and have the common black out problem probably cause by a loose connection(s), i figured i would examine the inside of the cluster and maybe see if i might be able to re-solder the connection points or not. If anybody has a diagram of the circuit boards, wiring arrangement, etc.. it would be greatly appreciated, Thank you, Chase

Ok so ive gone through and cleaned out the connections and bent a few pieces BACK in place in my cluster and my guages turned on great for many days then went out again! I dunno what to do i cant really affored to send it in (im 18), has anybody else had success doing the same thing? Is there something else i should have done while i had it pulled apart?
