Larry.I just metered the track plugs. The 2 pins next to the capacitors go to one side and the other 2 go to the other side. Also the lighting voltage is 5 volts not 12. Alan.

Larry, The right side wires go to the rear or Capacitor end. In the files area there is a file called Quantum1Lighting_1_1_1.pdf that shows all of the connections. It does not show which wire from

Thank you TCC, So its a three chime D# minor dominant. I will try playing K3H, M3H and S3K sound files and compare with Youtube video recordings of Ontario Northland. Regards Alex

Alex; As these are Canadian units, they will have the Canadian D# minor chord. Quite harsh and not a US sound at all. From looking at pics it appears to be a Holden (Nathan) K3HR. Maybe Dan can

Dan, Thank you very much. I will load those files into Q1a programmer and test. I bought those Ontario Northlander P2K units at the trade show in Woodstock Ontario. Therefore I can not say if the

Alex, After looking at a number of photos online, it appears these locomotives have a 3 chime horn, although I don't know which one. My sound file recommendations are either 112-12 with the Nathan

Group, I have a very old BLI SW-7 that has run very well for a long time. It still runs very well, but every once in a while the speaker will emit a random burst of static like noise. I actually

Hi all, I have two P2K GP9II HO units of Ontario Northland. Does anyone know the horn type used by Ontario Northland. QSI produced number of q1a sound files related to GP9 diesel. Which one is the
