All instruments dead in 87 5000TQ

[Peter Golledge]

Listers,

All of a sudden I have no speedo/fuel readout.  Don't know about the
Temp
or Tach as this is the LT1Q and those have never been connected.  The
backlighting
and the Auto check works fine.  Fuse is fine, brake lights (same supply)
are
working fine also.  I pulled the cluster and reset all of the connectors
to
no avail.

Any BTDT?

Thanks
