Problem. I replaced the old rectifier disc with a 10 amp axial silicon diode in my LW transformer. Running PW loco and tender. The old rectifier did work and the whistle sounded similiar to my CW-80. After replacing it with the diode the sound was anemic and the loco would stop as if not enough power. Without the loco on the track the whistle needed the throttle at a higher setting compared to the rectifier disc. As I stated the loco lost all power and the whistle barely sounded even close to a high trottle setting. I did read that most use a 6 amp diode and even higher. I installed it with the red wire from the terminal windings to the anode and the cathode to the switched resister wire. What am I doing wrong?

The LW can be tricky to put back together. Did you make sure you got the reed switches under the whistle button back in the right position? Sounds like maybe not?

Which diode did you use?
I know the ZW and KW users use the 1N1190AR stud diode as a drop in for the 1041-13 rectifier. Since the LW uses the same rectifier, I suspect the same diode would be sufficient, if not slightly overkill.
I have to try that soldering the cathode to the plate.
Success, yes. Thanks PLCPROF.
Glad you got it working!
