Hi Folks,
This is my first actual post and is a plea for some knowledge, or maybe a warning to others.
I recently tried to 'improve' Mainline class 42 by adding a generic home made keep-alive. After finally identifying the negative connection to solder to I gave it a try with a Hornby R8249 decoder. It worked well and I gave it a quick 'body-off' test run, vastly superior to before. Cue cheers and champagne etc.
However when I retried it later the thing was dead. I suspected I may have shorted something when retrieving it from the track. (I tried the decoder after on a test bed..it's knackered).
Trying to be positive this weekend I tried again(more carefully) with another decoder. All was well till I gave it a retry before buttoning it up, dead again. I suspect decoder blown also. This is getting to be expensive. Any clues as to why this is happening anyone?
