You mean there’s MORE of these chips? It’s a PS-1 Reset chip, apparently.
Ok, that’s enough. The seller will accept a return so that’s my preferred option, although I COULD just wire the pickups straight to the motor and run it on DC - there are uses for a loco like that in UK
Having read the manual, I can’t imagine how anyone ever thought that any part of this system, was a good idea. I’m very unimpressed with it; I have a 12vDC BLI 2-8-0, and HOn30 loco, with a QSI chip actuated by DC on/off pulses and it works very well.
