[TR] TR3 Fuel gauge test

[wbeech]

Here is a good detailed site to show you how to hook up everything to test
your guage.

IMHO, you still have a sending unit problem, be sure all the connections are
good on you test leads.  On my sending unit, when it did not work, I found
the very fine coil wire had broken loose from the solder joint, added a
short length of wire and resoldered & Bob's your uncle!

Well I ordered a new sender unit from Moss & when I tested fresh out  
of the box I got 0 Ohms resistance no matter where I moved the float.   
But given that the resistance device sits down in the gasoline I thought I
would try in in my 2/3s full tank.  Still getting 0 Ohms.

Before I called Moss I wanted to test the gauge as well.  So I thought I
would go down to the local Radio Shack & buy a couple of resistors to check
it out as well.  Since the gauge is supposed to show full at about 70 Ohms I
thought I would try to get something close to 70 & something around 35.
Given I took my last physics class 40+ years ago any advice would be very
much appreciated.
