NormanQ4 Posted August 2, 2015 Share Posted August 2, 2015 I initially installed a Hatton's 8 pin direct decoder in my R3086 Flying Scotsman.One day it just stopped running.I changed over to another Hatton's decoder from another loco and it then ran okay.Returned the decoder to Hatton's for replacement and decided to replace it with a Zen360 decoder with stay alive.Installed the Zen decoder in F Scot and it read okay on the programming track.Placed the loco on the regular track and nothing happened.Returned the loco to the programming track and reprogrammed it with a new ID and still nothing happened.Switched the Zen decoder to another loco and nothing happened.Both locos then ran okay when using the Hatton's decoder.Can I be unlucky enough to have a faulty decoder replaced with a faulty decoder, or is there a simpler explanation and solution?

AncientMariner Posted August 2, 2015 Share Posted August 2, 2015 Both locos rune with the Hatton's decoder - conclusion: locos definitely OKNeitther loco runs with the Zen decoder - conclusion: decoder probably faulty.Try a factory reset on the Zen decoder (the manual will tell you how). If nether loco runs then your conclusion above seems likely to be true - 2 duff decoders.AM Link to comment Share on other sites More sharing options...
Nick_ Posted August 2, 2015 Share Posted August 2, 2015 Set CV8=008 to reset the Zen decoder and then try running the loco using the default address 3. If it works then re-program it to whichever address you want to use and hopefully all will be OK. If it still doesn't work then it looks like another faulty decoder.

AndrewP Posted August 22, 2015 Share Posted August 22, 2015 I had a problem with CV29 being corrupted on my decoder after setting the loco id - I reset the decoder (by setting cv8 to 8), then read CV29, set the loco id and reset CV29 to it's original value (6 in my case) - that fixed my problem - the lights weren't working properly. -Andrew Link to comment Share on other sites More sharing options...
mad trucker Posted August 23, 2015 Share Posted August 23, 2015 Hi i recently got a job lot of hornby bit on eBay.in the parts was a hornby sound tender, looks like it was from a princess/duchess class. I have a hornby princess gold set r1170 which has never been run and was hoping to put the sound decoder on to it.seeing as the tenders look very similar i tried to couple it to the train to see if it worked, but got no response. It won't accept a loco no from a dcc controller. Is there any way of testing a decoder or does it have to be sent back to the manufacturer Link to comment Share on other sites More sharing options...
