W126 with fluctuating gauges
 

My 350SDL gauges occassionally lose power ... I have not done any troubleshooting, yet. After a while of no power, they then power back up.

Tach dies (assume it's AC?) and the other instruments freeze (DC?) ... can't recall saying and I may get it backwards, but ... "DC lies, AC dies?"

Anyone else had this same problem? I will check the fuses first and then work back towards the instrument cluster connection ... maybe do the ground check thing ...

Any suggestions?

Thanks!
