loco hesitation

greenspun.com : LUSENET : Wiring for DCC : One Thread

I have installed a Zephyr and have two reversing sections. I just set up the PM42 and changed the settings as per Digitrax's Application notes. As per the trouble shooting I checked the CV's for accel and decel and found them to be at zero.

At this time I have only two locos with decoders (installed by me) DH123's. In both cases at low speed as the loco crosses the rail gaps it hesitates and in some case stops at the gap. (The locos are an Athearn SW/1000, at tight fit for the decoder and a Bachmann Spectrum K4 Pacific DCC ready, a plug in)

Any ideas or hints or is this normal

No, Stopping or hesitation at reversing loop gaps is NOT normal. There should be no perceptible interruption of power as the loco rolls over the gaps. Do you have the rail gaps opposite each other?

I am not a Zephyr guy but I would suggest looking into the set points for your PM42. I think the factory defualt trip settings are set to the max the Zephyr can put out (2 amps I think). I would look for troubleshooting articles for PM42 versus Zephyr. Perhaps Digitrax has a FAQ on the subject.
