I have a 1985 westy and the temp light flashes until the temp gauge is
in the center of its range.  I have shorted across the temp wires and
it  flashes until the engine temp gauge is in the center of its range.
The  bentley shows a COOL LOW LVL WRNG CNTRL UNIT  but I do not know
where it is located.  That is the next part that I will check.

Thanks
Steve
