 1.  Coolant level is low;
 2.  Coolant level sensor in overflow tank is bad; or,
 3.  Multifunction switch/sensor is bad.
 #3 is most likely, assuming all wiring connections are good.  These switches
 seem to fail regularly.  They go for ~$50.

i just replaced the multifunction sensor in my '86 5kTQ. i had the same prob 
as you, the coolant level warning light was coming on 30 secs after i started 
the car..  i went thru 2 good used overflow tanks before i got smart and 
replaced the multifunction sensor switch.  took less than 5 minits to replace.
