I a;so have his DCC Amp meter adapter. I connect that amp meter adapter to a PM128, 3 1/2 digit panel meter for constant monitoring

I have a LokSound decoder in the loco. The DC power pack feeds 13.55 volts DC to the controller.

One piece of calibration information - since you have a PowerCab, it has a built-in ammeter. How do the readings compare to Rob’s circuit?

I will have to do that. I made the DCC Amp Meter for our club layout that uses the 5 amp NCE Power Pro. We only run about seven sound engines at one time.

No problems at the layout. Just curious.
