John, I think you are getting it.? How could voltages be in places you don't expect?? If there is a wiring error.? I can't tell you how many times this has happened to readers.? This especially

Allan, You are right that I don't quite get it. I went back to the layout again and checked the power feeds where they would have gone to the RRAmpmeter (now out of the circuit completely) and using

John, I'm not sure you got it.? Set the RRAmpmeter aside. Don't hook it up.? With the wires that should go to the output of the RRAmpmeter, have them "dangle".? Connect your DVM to these dangling

I hope I understood your directions correctly and I did what you asked. Input showed 14.7 on the wires into the meter and DVM read 11.82vAC. . On the output side with the RRA connected the output

John, While you are waiting to get your RRAmpmeter repaired/replaced, I would check the wires you had hooked up to the output of it.? If you have a digital multimeter, set it on 20V or 200V AC

Thanks for the advice Allan, and I did as you suggested. And unfortunately I got 14.2V and 5.22A when completely disconnected on the output side. So I believe your diagnosis of a damaged meter would

Hi John, I've not had a bad RRAmmeter.? Anything is possible, but it is more likely that at some point, it was wired into your layout incorrectly. For any electronic or electrical device, do not hook

Thanks Allen. I’d love to have a second (let alone four), as I could swap one out and see if I am the problem or is the meter the problem. So I’m wondering if you have ever seen a RRAmmeter fail?

For those that have never used this meter, check out the online instructions for the RRAmmeter on Tony's Trains website. It is a combination DCC voltmeter and amp meter.? It has two displays and when

Sorry for the lack of clarity, so I'll try to be more specific. I'm using a RRAmpmeter which has pairs of contacts on the left hand side and the right when looking at the digital readout. Connecting

Same as Wouter, I don't understand your meter or its connections.... An additional thought: if you've been measuring short circuit current, then the DCC system should have been giving a short circuit

John, The "two wires in, two wires out" description is beyond anything I can imagine a meter would be like, so I'm afraid I'm going to ave to leave it to those who understand your setup and/or meter.

I neglected to say, once you have the meter working properly with a loco on a test track, you will have confidence that your meter is working correctly and you are hooking it up correctly.? Then you

John, Are you using a DCC Specialties RR Ammeter?? If so, it is indeed two wires in and two wires out.? Consult their documentation for clear diagrams on how to hook it up. As others here have

Wouter/Don, Your responses are similar so in my layout, I do the voltage across the rails, as indicated, but for current, I was putting the meter in line with the bus wires, i.e. two wires in and two

John… it sounds like you are connecting the ammeter essentially rail to rail rather than in series with one of the booster to track leads. That is why it is reading the full output amps of the

Sounds to me like you are shorting the Power Pro with the amp meter. For voltage, the meter must be across the track, for current it must be in one of the power leads. Voltage: | | | track | Power Pro

John, It does seem you might be reading the short circuit current limit, which would happen if you connected across the rails, same as if you were reading track voltage. You need to open a connection

Think of a garden hose. Amps would be the equivalent of how fast the water is flowing. Generally speaking that would be the same speed throughout the system until you reach a "branch" where each new

Hi! I’m looking for help with my DCC Ammeter. I have had it for number of years and used it as a voltmeter only while building a large layout to test for power, shorts, reversed wiring in hand-held
