So I installed a whistle I found at the local hobby shop a few months ago into my 259's tender. Problem is... when it's hooked up to the locomotive and in motion, it shorts quickly as soon as I press the button then works fine, it does this about 75% of the time. I can't replicate it while pulling the tender with my hand or sitting still. I ran the them with the lights off and there doesn't seem to be any sparks occurring between the loco & tender. Anybody have any ideas?
