All,
Got the parts in and got everything soldered in place....

To Recap on its replacements;
R13 - Metal Film Resistor 51R-3Watt - Replaced with Metal Film Resistor (51R) - Part # RR03J51RTB

R01 and R02 - SMD Thick Film Resistor- 51R - 3 Watt - Replaced with Part # 352251RFT

C41(original locomotive one -it popped) - Electrlytic capacitor 330uF 63 V - Replaced with Panasonic 330uF 100V - Part # EEU-FS2A331L

I replaced also the C34 - Electrlytic capacitor 330uF 63 V - Replaced with Panasonic 330uF 100V - Part # EEU-FS2A331L as well.

C24 - this one originally disengrated to nothing - thought according to Diagram to be CBB 2.2 uF 100 V - The capacitor was a SMD...I bought a 2.2uF 100V C1210C225K1RACAuto.

The SMD I purchased was way bigger in size. I went to place it on the pads and it completely covered it and then some.

I had some 25V 4.7 uF SMD (C0805C475K3RACAuto) and the thing was correct dimensional wise...So I am not sure if this will cause me havoc or not.

With that said...I fired it up and it appears to be cycling (Below is a MP4 from my google drive of what its doing);

Is this a Bridge Rectifier issue?

Any troubleshooting tips...Please...

Thanks again!
Chris
