I have been getting this '84 4000 quattro back on the road for its new
owner.
It is (CIS E) model.
Where is the sending unit for the water temp. guage? Is that contained in
the same two prong switch on top of the cooling neck below #1 cyl. Do
these/does this pass current to ground or ?? Bently is not clear, but that
is what diagram indicates.
Reason for question(s) - the temp guage is not registering temp and the
overheat warning light starts to glow but only dimly when hot/fan cycling.
The oil pressure warning light goes on at around 2500 rpm too with engine
cool, and when warm, many of the lights start to glow with the oil p. warn
light when engine revved. Wiring problem with the instrument cluster, or
multiple sensors going kaput?
I have been ironing the glitches out of this '84 4kq that has been out of
service for over a year. Engine runs good after replacing thermo-switch
and replace vacuum lines, etc.
