Herri Posted August 3, 2022 Share Posted August 3, 2022 I have just purchased a Bachmann Cl 45 with ESU sound. The loco runs fine with the sound switched off. When I switch the sound on, it will only crawl along. It does not react to the throttle at all. All the sound functions work ok. I have tried looking (and switching on/off) the functions with the ESU programmer software. I have reset CV8 to 8. No change. Any ideas? Link to post Share on other sites More sharing options...
charliepetty Posted August 3, 2022 Share Posted August 3, 2022 Is the decoder a V4 or V5 and how old is it. Charlie (Legomanbiffo) Link to post Share on other sites More sharing options...
Herri Posted August 4, 2022 Author Share Posted August 4, 2022 It's a Loksound 5 DCC, purchased 3 weeks ago. Production date of decoder July 2021 Link to post Share on other sites More sharing options...
charliepetty Posted August 4, 2022 Share Posted August 4, 2022 OK. This should be covered by the ESU Warranty scheme if the supplier will honour this, firstly try a CV8=8 Reset which 'Might' solve the issue. We could look at it for you if you want ???

Herri Posted August 4, 2022 Author Share Posted August 4, 2022 Thanks. I did try the CV8 to 8. I live in the Netherlands, and dont want to send it anywhere as its too much hassle and expense. I'll try and contact Bachmann. Link to post Share on other sites More sharing options...
meatloaf Posted August 4, 2022 Share Posted August 4, 2022 Have you checked drive lock isnt enabled? Link to post Share on other sites More sharing options...
wiggy1 Posted August 4, 2022 Share Posted August 4, 2022 Did you use your controller to do the CV8=8? Did you recycle the power after you did CV8=8? Wiggy. Link to post Share on other sites More sharing options...

I have heard of this but cant find any reference in my function list from Bachmann. I have looked in the Loksound 5 booklet from ESU but again cant seem to find any thing.

Not exactly sure what you mean. After writing 8 to CV8, I took the loco off the rail. Closed the programmer software and restarted. Placed the loco back on the rails. No difference.

Herri Posted August 5, 2022 Author Share Posted August 5, 2022 Another weird thing: When the sound is on and I let it run (it crawls), I turn the power down to zero and it just doesn't stop. Just keeps on running, although the speed scale shows zero (ESU Drivers cab) Link to post Share on other sites More sharing options...

Could be F5 maybe? Link to post Share on other sites More sharing options...

Herri Posted August 6, 2022 Author Share Posted August 6, 2022 I have found the reference to F5 but unfortunately it does not make any difference, if I press F5 or not. I cant find any mention of this "Drive hold" in the ESU programmer or booklet. Link to post Share on other sites More sharing options...
Hamburger Posted August 6, 2022 Share Posted August 6, 2022 In the ESU forum there is an offer to help you ... Link to post Share on other sites More sharing options...

I cant find any mention of this "Drive hold" in the ESU programmer or booklet. I suggest you try the decoder on another 21Pin model and try another 21Pin in your Class 45. This will see if the decoder is at fault or the loco is at fault. If there is no change then use your lokprogrammer to 'Reblow' this decoder with a new Class 45 sound file. These can be obtained by E.Mail from: https://www.dckits-devideos.co.uk/index.php?route=product/product&path=253_69&product_id=74 Hope this helps.

Herri Posted August 6, 2022 Author Share Posted August 6, 2022 Thanks to all who helped. I have now found out via a couple of guys on the ESU forum, that somehow the shunt (or drive hold as Bachmann calls it) was mapped to the F1 button. This was not visible on the function mapping page. Hence I couldnt see it. Works fine now😀 1 Link to post Share on other sites More sharing options...
