I finally solved the continuous blinking red light on the 84 temp guage by
replacing the temp guage (which has a built in electronics circuit in it)
with a used but otherwise good guage.  Now the replacement is doing the
same thing, blinking all of the time.  Does anyone have any experience with
replacing the temp guage?  If I purchase a new guage from the dealer, will
it suffer from shelf age and go out the same way?
