Hey guys, just picked up my first Z. Digital dash not working as far as speedo, tach, or any other vital gauges. However, headlight, tail light, turn signal, cruise control lights come on with no problem. Wondering if anyone else have had similar problems before I start poking around aimlessly at fuses for hours on end? Pertaining to an 85 z31. Thanks!

 

could be the power supply is shot but get out the vom and check the fuses and the fusible links. none of the stuff that works has any bearing on the digi dash display.
