Sound of Steam diode problem?

Wolfie11OGR Forum Member

Hello and thanks for welcoming me aboard. This is the forum to go to for all my train wants, needs, ideas and most importantly , answers...

I recently purchased a mid 70's 8603 4-6-4 w/ C&O sound of steam tender . The sound did great at first but I read to replace the foam insulating pad which I did with thin cork.. In cleaning the old foam debris, I may have inadvertently caused a malfunction. Now when I run it with the 8603, it seems to take power from the Loco so much I do not run it. When I bench test the tender, it works fine. Just an issue with power or ground backfeeding to the Loco. I noticed 2 tiny diodes in the beginning of the circuitry. I'm wondering if 1 of them is letting ground, common?, back to loco? Any help would be appreciated. Thanks
