Building a classic cab unit–the MLW FPA-4: Pt. I Wiring diagram CV‘s and manual address calculation
CV17= 218 6782÷256 = 26 quotient, 126 remainder CV17= 26+192= 218 (6782 is desired address)
CV18= 126 Check: (CV17-192) 256+CVG18 = (218-192) 256+126 = 6782 (locomotive number/address verified)
CV29= 38 (26h) No speed tables, dual mode, 28/128, normal dir. CV2= 0 V start default= 0 CV3= 5 Accel rate default= 0 CV4= 5 Brake rate default = 0 CV30= 4 Functions F5-F* swapped with F9-F12 (default= 0) CV115= 13 Air horn default= 9 CV114= 5 Bell ringing rate default= CV130= 128 Bell vol. 0-255 (default= 128) CV128= 192 Master vol. 0-255 (default= 192)
Auto sounds CV193= 0 Auto bell on (default= 15) CV194= 0 Auto bell off (default= 19) CV195= 0 Grade crossing airhorn sensitivity (default= 4) CV196= 3 Brake squeal sensitivity (default= 3) CV197= 0 Analog mode auto sound config. p.85 (default= 0) CV198= 0 Digital model auto sound config. p. 86 (default= 0) CV63= 20 Analog mode v meter start (default= 20) CV64= 180 Analog mode v meter max. (default= 180) CV129= 225 Horn vol. (default= 225) CV116= 36 Engine exhaust control (default=39) 36= throttle notch/4 speed; was throttle notch 7 speed
handy for this. Paint the cab interior (an “industrial light green” color is ap- propriate) and the crew figures, too.
