03 e500 cluster
 

Here recently the benz has been sitting due to exhaust leak. Ebery couple of days i go out and start it. But this last time eberything was perfect excelt the cluster was completely dead. Not a single light or needle working. I tried the fuses, unplugging neg.terminal on main battery and charging 2nd battery. Still nothing. Has anyone had this happen where it goes completely dead and were able to fix yourself. Also if you know of any good places to send the cluster off to get rebuilt that would be great to. Thanks any help is appreciated
