KB97 Athearn N-Scale FP45 / F45

What Digitrax decoders work in the new Athearn N scale FP45? We recommend the DN163K1C, following the procedure below. One of our editors was able to successfully install both the Digitrax DN163K1B and DN163K1C decoders in the unit. We have determined that the chassis design requires that the decoder be installed backwards. The only problem this poses is that one additional step has to be taken when programming. Both the DN163K1B and DN163K1C decoders are the same footprint with the exception of the LEDs. The DN163K1B has T-1 3mm LEDs and DN163K1C has surface mount LEDs. When the K1B version ...

KB356 DH165A0 - Headlight brightness

I am installing a DH165A0 in an Athearn SD70. The head light outputs are a nominal 30 ma (with the link cut). The bulbs were of course a bit lower in their current demands and were very bright for a short while. Is there any way to lower the current output from 30ma or do I need to add a resistor in line with the bulb to drop the voltage output? Of course if it is supposed to be a regulated current output this might be a problem. The DH165A0 has a constant current source for F0F and F0R, so ...

KB401 Life-Like N-Scale GP18 Modifications needed for the DN163K2 decoder

The Life-Like GP18 locomotive can be modified to accept the DN163K2 board replacement decoder. The locomotive samples used by Digitrax for this instatllation needed to have the frame engagement clearance slots under the cab on the fireman-side widened about 1mm towards the rear of the locomotive (long hood end). This can be done with a small file or Dremel type tool, to allow the decoder to properly engage the casting with the power tab on this side. The engineer-side slots are OK to fit the decoder power pickup tab on this side. Be sure to check the motor tabs are safely ...
