Temperature senders.

[Chris Wilson <chris@maximum-bhp.u-net.com>]

1987 UK spec 200 turbo 2WD.What are the senders around the top rad 
hose to head area?

3 with 2 wire connections,one big `un with a multi plug on it,which is 
lowermost,and further forward,a small,single wire sender,which I 
assume is the temp gauge sender.(The gauge doesn't work,and earthing 
the single connection sender cable only sends the gauge quarter way 
up.

I now suspect the gauge itself..Fuel gauge is fine,so I don't think 
it is an instrument panel voltage regulator fault.

In case it is the gauge,will a (commoner over here) Audi 100 gauge be 
the same?

Thanks guys.
