1934 dual temperature gauge
I have a dual temperature gauge for my 34.
It has been hanging for some 18 months with the gauge portion at the top and the sender unit straight down below.
Upon testing it recently before I install it, there was no red fluid showing (it did used to show).
I inserted it in boiling water and the fluid started to show, but only a small way put it in cold and it disappeared.
Repeated the procedure some more and the same happened.
Am I doing something wrong or do I have to something else to make it travel further up?
Any help appreciated.
Thanks
Graham
