Subject:      Need help with blinking coolant overtemperature light

My 84 camper has been blowing the voltalge stabilizer about once a month
for the last six months.  I would loose the temp. gauge and the fuel gauge
in the usual manner.  Sometimes when the stabilizer was about to blow and
the voltage dropped down to around 8 volts, the red light would begin to
blink.  I now have a heavy duty 10v regulator in its place, and it hasn't
blown yet.  I have a 1 amp. fuse in the line just in case.

Things started OK, but after about an hour of driving the red light started
blinking and won't go out like it should after starting.  The temperature
gauge and the fuel gauge are operating normally.  I have read everything in
the archives that I can find.

One message said that the coolent level sensor should read 31K to 65K ohms
and that too much antifreeze could cause the light to blink.  I tried
unpluging the cable from the sensor and shunting a resistor in this range
across the plug.  The light still blinks.

One message said that the cool low level warning control unit should be
replaced, and that it was located behind the fuse panel.  I removed the
fuse panel and unpluged every little box one by one.  The light still
continued to blink.  I never could find anything that I thought was the low
level warning control unit.  The Bentley on page 97.10 shows the Fuse/relay
panel and indicates what each of the relays are, but doesn't show a coolant
low level warning control unit.

I have red the Bentley from cover to cover trying to find the location of
the low level warning control unit so that I could see about replacing it.
One message I read said that a change was made around 86 to move the low
level warning control unit to a board in the dash, but I have an 84.

HELP! I'm afraid to use the van for an extended trip because I can't tell
if I have a problem or not.  Any ideas would be appreciated!
