volt and amp meter connections

ok so bare with me, I'm an idiot with these things
I bought two DC volt amp meters from amazon from the suggestion of Daryl Krause web page
So I know its DC volts , so where in my system do I connect it.  I have 2 DB 150's that i am taking out of hibernation and setting up for the
 new layout.  I am soooo confused as to where on the booster or command
 station to hook these up.  i am using the original power sources from digitrax PS515 and a Loy Toys power supply. and an original PM4.  they all worked about 5 years ago.
So i just want to know how to measure my system performance with volts and amps.  Can someone draw me diagram of the connections points please.
I hopefully am able to upload a picture of my new power station.  thanks
Miguel

Since you cannot accurately measure the power (current and voltage) at the track DCC output, you need to install them at the output of the power sources.  But I recall that some of the early Digitrax systems used AC power sources.

Are the power supplies providing AC or DC power to the DB150s?

yes its AC.
 I just reviewed the youtube video and he is using the 210 and 240 boosters which are DC supplied.  So i guess I need to get AC volt gauges for my old equipment

If you want to accurately measure power output (both amps and volts) AT THE TRACK, by far the easiest and most accurate way for the non-electrical engineers among us is to buy the DCC Specialties RRAmpmeter II.  It's about $100 at most e-tailers, but if you want accurate information about what's going on AT THE TRACK with your DCC system, this is the way to go.
