Hi All
I'm building a control board for my model train layout. I would like to add a voltage meter for each of my tracks. (4)
As the tracks each have a reversing switch which reverses the polarity to the track.
Would a 2 wire volt meter be able to work with reversed polarity or do I need to use a 3 wire volt meter to cope with the reversed polarity.
Or could I just add the 2 wire volt meter to the rotary power controller .
cheers
