Thanks for your help Stan. 👨🎓
I had to put the switcher aside for awhile. 😩
I've run 7 engines on this same conventional O27 test track performing normal maintenance while I was at it . 1 was a ps2 /3volt USRA 2-8-8-2 and 6 were ps3 steamers and diesels. I had perfect results from all of them.🤔
Sometimes you have a good day........ .............one of the steamers ( RK Pennsy tuscan color ps3 4-6-2 ) had no marker lights , no fire box glow and from when it was new always had somewhat kind of a scratchy sound to it..................so I had to get back to work?.................marker lights connector wasn't tight , wire and bulb replaced with a new wired bulb and replaced the 4ohm 4watt speaker with a known good one . Everything came out well. It was a good Saturday. 🙄
