I bought one of these little digital voltmeter and ammeter gauges, is this best to insert in the black wire of my DCC bus or the red wire? The circuit diagram suggests it should be after the load, which would suggest the black wire (?) Not sure if the voltmeter will work, or what it’ll read if it does work, but it’s the current I’m most interested in 🙂
