So it is a "real" short causing the breaker to trip. I'm still not sure how upgrading the microcontroller chip on the decoder can fix the problem. The only possibility I can think of would be if someh

There seems to be some confusion with terminology. "Short circuit" implies an electrical problem when there is some very low resistance (close to zero Ohms) between the rails. It is usually a physical

That is really the easiest and least painful solution. That is the reason I still have computers at home running Win98SE and XP at home. Those vintage computers painlessly handle all of my "legacy" ha

Bruce, QSI decoders have hundreds of indexed registers. Some are single-index, others double-index. With CV Manager reading them all is a breeze as the program figures out all the indexing. Manually a

Bruce, if the loco moves (motor can be controlled) but it is silent then F6 will nto fix the problem. You might want to get it out of the consist and try F8 (the sound muting function). Also pressing

NIck, Regardless of where you got your information, my objection was to this statement you made: I don't know who sent the 10 Ohm resistor but it certainly was NOT correct. With that HIGH value resist

Colin, Wirewound resistors are usually rather bulky, and they are designed to dissipate lots of power (they basically act as miniature electrical heaters). I don't know the power dissipation rating of

I have the Q Programmer, but it works and I never had to take it apart.. Couple of comments: Colin stated that the original resistor was labeled as 2R0. That is 2 ohms, not 1 ohm. If the resistor in q

Not quite. There is always full voltage and current available at the track, and both decoders power up (their microcontroller circuitry) immediately. Of no momentum is configured, both sound and non s

CL2 is possibly a device called "constant current diode" (Google search will show you examples). That device itself needs some voltage across its leads to operate properly. Same with LED current-limit

So after you double-press F6, then press F10, what does the decoder say about its current status? Or does it pronounce the locos address? Make sure the loso is in "neutral" or stopped (speed step 0).

Well I learned something new today. Thanks for the gift of knowledge! And it isn't even Christmas yet. :-) I have heard of Atlantics, Pacifics, Mikados, and even Mud Hens, but a Minaret is new for me.

If you have either steam or diesel sounds coming out of your Minaret then you are in big trouble! :-) (Yeah, I know -- blame it on auto-correct). Peteski

Ah, now you have a very long MOOOOOOOOOOOOOO! Life is good! :-) Peteski

Hi Mike, Looks like you did figure it out correctly. Here is my take on the circuit (which agrees with your earlier speculation). Just to verify, take a ohmmeter or continuity tested and check whether

This task would be easy if you could take better lit closeup photos of the top end of the board where the connector with 2 black wires is, along with the 2 large cylindrical components (electrolytic c
