GTV-6 Speedo

[Kevin.FILLIP@domain.elided]

     Can anyone tell me what to check on a speedo which will occasionally 
     die at startup on my '85 GTV-6. I've already replaced the #7 fuse on 
     the panel. This is an intermittent problem which only happens at 
     startup (ie. the speedo either works or doesn't). I checked the Car 
     Disc but could not find a wiring diagram for the speedo. Thxs.
