I inherited a LL SW switcher with a non working QSI decoder. It appears to have been rewired so I wonder if someone could tell me what is supposed to be connected to the 6 pins on the P1 and P2 connec

Positive news. I was able to revive the "dead" decoder in the Atlas gold locomotive. I removed the chip and installed it in the socket in a similar chassis (had a reed switch). I was able so see the c

Yes, I did try to to reset the decoder using the 3 cv procedure on both the programming track and on an isolated section of main track using address 00. Unfortunately, neither seemed to make a differe

I have disconnected one end of the reed switch on both locomotives, but it doesn't seem to help

I have 2 QSI equipped P2K locomotives that no longer respond to either DCC commands or an inquiry from a QSI programmer. I have verified that there is continuity from the track pickups to the connecto

The procedure for using the new sound sets seemed to work ok and it was great to be able to listen to select from a list of prime movers, horns, etc. The only problem I encountered was trying to add m

Probably bad terminology on my part The title of the paragraph on the QSI web page is "Cut and pastable sound sets for Q1a .... equipped with factory QSI sound". It goes on to say "the following Q2 fi

I would like to reuse a chip I previously had in a reed switch equipped locomotive and was programmed with a Q1A sound file The new locomotive has a volume pot and I would like to put in the new Q2 pa

I have some salvaged boards which need new plug in harnesses to be functional I searched the archives but couldn't find a source for these or the specification so I could try to find some at one of th

I would check the value in CV11. Change it to "0" and see if that helps Tom in Texas

I have a pair of older (version 6 chip) P2K GP9 chassises which were configured to run with the long hood forward If I purchase one of the new chips, can it be programmed so the lights operate correct

After almost giving up on a P2K locomotive with a QSI decoder, I decided to go back and retry the "DC" reset procedure and it worked. My "conclusion" that you must wait at least an hour for the capaci

I noticed that the QSI equipped Atlas MP 15 locomotive I have has a noise suppression capacitor attached to each motor brush. I know they recommend removing these on Bachmann Spectrum locomotives and

I am working on a BLI unit with a version 6 chip which seems to go stupid every time I try to change a CV using OPS mode programming. I disabled the reed switch but it didn't seem to help I am using a

The decoder in question is in a Walthers high hood GP20. The engine is brand new. Wheels and track are clean/ An identical engine purchased at the same time works fine On a programming track equipped

I had the same issue when I went to put an 8 ohm high bass speaker in a QSI F unit (probably not a Q1A). The suggestion I got was to add a 1/2 watt or greater 8 ohm resistor in series with the speaker

Yes both of the "problem" engines respond correctly to functions like F1 and F2. I tried using the value of 128 you suggested in my F7, and the engine responded with the word "reset" after I entered t

I have 2 friends whose FP7's act like they are in disconnect mode (sound but no movement) but don't respond to double pressing F6 or receiving the reset instructions from changing the 3 CV's listed on

Thank you for the information.? I have a couple more questions Does Q1 refer to an OEM style board with a replaceable chip? Since JMRI doesn't have the specific profile for this decoder, can I assume
