John;
If the wire between your gauge and the temp sender gets shorted to ground
, or if the coolant level sensor becomes disconnected,  you will get the
same symptoms. Since it should be pretty obvious if the level sensor is
un-hooked your problem is likely to be the temp sensor. That sender (on
our 85) is near the water pump/ thermostat. It has a single terminal
that looks like a nail head.  Locate it. Find the wire that should
attach to it, it is probably making contact  against the engine . If it
is attached disconnect it. Is the problem gone ? the sender is shorted.
Led still flashing?  Problem is upstream , look for a pinched wire. Let
me know.
Good Luck
