OK, this is strange.? I know stuff happens.? I put my engine(Walthers Proto GP-60) on an isolated programming track and started DP.? I went in and read CV 29 and lo and behold it was 2.. It was supposed to be 34.? So I changed it and the engine responded properly to its 4-digit address with both WiThrottle Lites and Digitrax DT-500 throttle.? Is possible that CV 29 spontaneously changed?? Yesterday I was running engine with WiThrottle Lite and the DT-500 when it quit responding to 4-digit address.? Is it possible the decoder(factory installed tsunami) is failng??
Thanks for any responses.
