Transformer Question

[Jeff Brown]

Easy. Take an ohmeter and measure the resistance between diferent
combinations of the 2 wires. When you have two wires with the greatest
resistance between them, the center tap is the other one. What you have is
this:

A-----r-----CT------r------B

where 'CT' is the center tap, 'A' and 'B' are the other two wires. There is
a D.C. resistance 'r' between 'A' and 'CT' as well as between
'CT' and 'B', so the resistance between 'A' and 'B' = 2 x 'r'.
