Need a sanity check on my power upgrades (Digitrax Zephyr to DB150)

<p>[quote user="rrinker"]</p> <p>It is possible for it to be a short, since the entire motor shaft and gear train will shift one way or the other under hard starts and stops - although if there is that much play in the gears, it will do it under even moderate acceleration, and even slow acceleration if there is a decent sized train hooked up.</p> <div style="clear:both;"></div> <p>[/quote]</p> <p>Is this common enough that two different locomotives (the GP15s were not on the property the last time this was happening in March - the locomotives in question were a Proto 2000 GP7 and two Atlas B40-8s, all with DCC, no sound) could have this same problem, with slow acceleration and a heavy train? </p> <p>[quote user="hobo9941"]</p> <p>Walking zeros, or walking ones, doesn't make much difference. If you are drawing too much power, it would appear the same as a short to the Zephyr. All my locos have sound, and I can run four. When I try to run five, the power cuts out intermidantly. If I run the passenger train with lights in it, three locos are the limit. Somehow, you are exceeding the limits of the Zephyr system.</p> <p>[/quote]</p> <p>This is contrary to what everyone else has told me so far, except the other two operators who told me the exact same thing after experiencing the problem...who should I be listening to?</p> <p>---------------------------</p> <p><b>What I really want to know is - can a sudden change in current draw fool the Zephyr into thinking there's a short?</b> Or is it a short inside an overstrained locomotive mechanism?</p>
