In my continuing quest to learn more about electricity I got a basic voltmeter at the auto parts store.  I read the instructions and watched a You-Tube.  Then I measured areas on my layout loops which are all powered with individual CW80's and I got a nice consistent voltage around the room going up to almost 14 depending on throttle position.  I read somewhere that 14 with a basic voltmeter is really about 17 due to the wave of the power from a ZW80.  Then I tested the Polar Express track under our tree and it's 39-40 volts according to my $16 parts store voltmeter!  I used the same settings on the meter and went back and forth from CW80 to the PE track and consistently got 39 from the PE and a range from 0-14 on the ZW80.  The PE runs fine in both locations. Anybody know why the PE track reads so high?
