I tried different settings but it unfortunately continued to runaway at full speed without any input.  I might dismantle it and see what it will take to put a NCE decoder inside.

 Depending on what the value currently in CV29 is, subtract 2 from it to turn off analog conversion. This usually helps with runaways liek that, for some reason the decoder sees the signal it gets not as DCC but DC and if analog conversion is turned on it will take off at full throttle. This has never really made a lot of sense to me from a technical standpoint, since even if the decoder DID go into DC mode, the signal would be balanced and if anything it should sit there and buzz like a non-decoder loco does. But, it DOES work, so who's to argue with the evidence?

Bachmann GE44 switcher issue
Posted by cawayne1066 on Wednesday, April 15, 2009 11:23 PM

I have five DCC engines, four of them modified DC engines and one new DCC ready Bachmann GE44 switcher.  My four modified engines perform and behave perfectly but the GE44 when sitting quite happily at 0 power suddenly decides to go to full power and shoot around the track at top speed.  This has happened multiple times, unfortunately I didn't think about it at the time to see if there was something else occurring somewhere else on the layout at the same place on each occasion, right now let's assume it's random.

Any suggestions?

Thanks, Wayne
