You can get a decent voltmeter for around $25 at the local hardware store, Amazon etc. It comes in handy for trouble shooting and setting voltage to accessories as well.
By the time power comes out of my TPC unit I have about 16.5v to the track. My Legacy stuff runs just fine, I've had the voltage as low as 14v, with no discernable difference in operation.
I'd rather be a couple of volts low, than high. On a side note, most of my accessories recommend 10-12v. Accessory voltage is set no higher than 10. My accessories all work fine.
The voltage car is actually very close to what my multimeter was reading. That's what made me grab it and hook up to the track. Obviously analog vs digital makes a huge difference reading but still very close and definitely enough to make me go and grab my multimeter for the true track reading/to verify.
