[TR] Fuel gauge follow up

[John Gillis]

Taking Randall's and other advice I have been testing the gauge with  
the sender not in the tank, this allows me to move the float and  
observe movement on the gauge. I had already fitted a separate earth  
to the gauge as suggested and held the body of the sender to earth  
while testing. The gauge appears to operate backwards, as I lift the  
float the needle moves to empty, and vice versa. Having looked at the  
web site suggested I do appear to have a different instrument,  
although it is Jager with convex glass it has spade connections on the  
back, could this be from early TR4?. I had this gauge fully restored,  
if it is from a TR4 does it work in the same way? Hoping I have not  
wasted good money on restoring this fella!
