long island jack Posted September 26, 2022 Share Posted September 26, 2022 which decoder, which CV did you set? Link to post Share on other sites More sharing options...
Prof Klyzlr Posted September 26, 2022 Share Posted September 26, 2022 The decoder will likely be one of these https://www.modelrectifier.com/v/vspfiles/resources/dcc/0001906 diesel.pdf which, by all reports, are commonly ripped bodily from the loco and replaced with typically a TSU Genset or ESU LokSound V5 Genset decoder... ("MRC Decoders" and "good reputation for reliability" are two phrases rarely uttered in the same sentence with a legit straight face...). The fact that CV6, commonly "MID Speed Voltage", is repurposed as some MRC-unique "speed reaction curve" variable likely is not helping matters. I would strongly suggest following the manual's reccomendation to perform a factory reset: - Using a _Programming Track_ (NOT "Program on the Main") - Program CV125 = 1 - Tilt the loco off the track so one side set-of-wheels are clear of the rail, for at least 30 seconds (This is the decoder-equivalent of "have you turned it OFF and turned it back ON again?" power-cycle). - DO NOT adjust the Start Volts + Accel + Kick-Volts values (we are literally wanting to test and confirm Raw Baseline behaviour!) and retest...
