Perhaps the simplest way of debugging a problem like this is the classic ¡°halving¡± strategy. ?In short, disconnect half of your railroad. ?Find which half provokes your problem. ?Then repeat the process in the troublesome half until you locate the specific area that is causing your problem

On my NCE DCC Power Cab layout, after over 10 years of successful operation, my DCC locomotives began to reset the system after I had accelerated above 3 or 4 on the 28 speed setting. By reset, I mean that the system turned off and then went through its starting cycle.
Using my multi meter I looked for residence and found heavy resistance in one rail leading to a turnout. I suspect it must be the problem, but I don't know what to do about it. Should I make new wiring connections there? Should I get a new turnout? What is the best way to handle resisitance?
Additional info:
My layout is small. It's the Yule Central from the Small Railroads You Can Build, edited by Bob Hayden in 1983. It's an oval on a 4 x 6 foot table with two spurs, a tiny run around track, and a small two track stub yard. There are six Atlas snap turnouts and four DPDT switches for block control.
I coverted to DCC around 2010 by upgrading wiring. I installed a 14 gauge bus line and attached the 22 gauge feeders with solder and suitcase connectors.
I sent my PowerCab into NCE and they tested it and found that it was working perfectly (I have the 1.28C Chip). They suggested I test my decoders and wiring, and perhaps consider purchasing a Smart Booster.
Further testing my PowerCab system on an EZ Track oval showed my decoders and PowerCab were working fine. Some of my decoders required resets to factory defaults.
I tested my wiring for short circuits using the "quarter test," and each time the quarter was laid on both rails my system turned off.
