I have a1999 Jeep Wrangler Sport ,4.0liter , auto. Sometimes driving over rough road or on smooth road, the instrument gauges will go to zero , alarm lights will illuminate. Engine runs fine no other problems. Just tapping the dashboard will reset the panel! I am checking all ground wires and connections. This seemed to have started when I had an alarm system installed,though sometime much later.
