Hi all
Hopefully someone can help. I bought a Bachmann K4 today and after fixing the solder short on the circuit board in the tender I fitted a Soundtraxx TSU 1000 and 8ohm speaker. Tight fit, but after some surgery it all went in. Ran fine for about 3 minutes until the decoder overheated. I then taped the flat side of the decoder to a metal weight in the tender to help cooling as recommended in the installation guide, still over heated. I then ran without the tender body on for max air circulation, still overheated.
Surely the motor draw in these K4s isn't too much for a 1A decoder?
Any advice would be greatly appreciated
