Hey Bob, just an update.. been working on wires under the hodd and haven't had the dash apart yet but I have played with it a bit.. flashlight makes no difference, but if I put the 4WF on it goes dark immediately, stays that way and the t/s and high beam ind. light up.. Called a real corvette expert friend of mine back in N.Y. and he said first try disconnecting the turn signal switch and see if the lights stay on.. a short in the t/s switch will screw up the cluster lighting.

I also need a diagram of the fuse panel.. the chilton book generic pic. is worthless ( I also found errors in their wiring diagrams ! ) and I don't have an owner's manual for my '85... ideas?.
wish me luck, Later, Joe.|UPDATED|3/30/2014 12:32:05 PM (AZT)|/UPDATED|
Well, have more problems than I planned for.. Now I have the entire dash out, found some broken and bypassed wires.. repaired all that.. I think someone had the entire interior out, maybe this was a theft/recovery (and a bad job at that).. I asked for it !!!
So.. the latest on my dash issues.!!!!! Bought a Good Used dash cluster and guess what ?? It does the same thing.. Gauges working, no backlighting and t/s and 4 way indicators stay lit up.. So it's not my cluster and I may have a spare '85 cluster to sell soon...
I downloaded some wiring diagrams from batee.com and will check for a possible pos.(+) feed issue??. Any other ideas out there ?? Will let you all know what happens.
Wish me luck.. Joe.

Find one of these manuals. It has the wiring diagrams, and the most comprehensive troubleshooting info on the planet for these clusters.

NOTE: the Gauges /cluster lit up, all working O.K., still some to go
NOW hopefully I can put this back together ! Patience, Patience, Patience...

I think the car was vandalized and possibly a small gas fire under the hood.. Whoever put the interior back together was an idiot or didn't care and just wanted to get rid of the car.. The other idiot was me trading my '83 El Camino SS for it, but I just had to have another Vette.. and thank God I have the time and background to do it..
The good thing is everything is coming together and I learned more about these cars by taking it apart.. NOt that I would recommend anyone doing this just for the fun of it..
Hi everyone, just wanted to say Thanks for all the help I got online here..
All my dash work came out great (as usual) now can barely get in and out of the C4 anymore so it had to go.. Maybe if the doctors can find out what's wrong with the legs andI get better I wil have another in the future.. So I traded it away for a real clean 1983 Mustang Convertable. One more time I want to also thank Bryan at Batee.com too.
I will check in from time to time, but as always, If I can be of help to anyone, Contact me.
Best wishes to all !!!!!! Joe - Chino Valley, Az.
