2353 locomotive and dummy whistle issue

It sounds like the wiring is suspect.

The 'E' unit is always energized when the loco is powered up, but the coil should never burn out as it is designed to be constantly powered unless you lock it out.

Blowing the horn should not affect the 'E' unit, unless you press the horn button very slowly. There may be a very slight dead spot in the horn switch mechanism as the lever moves through it's full travel which may cause the 'E' unit to sequence if it is in the 'on' position.

To counter this, just press the horn button down quickly and/or lockout the 'E' unit.

Thank you Larry, 

I have the horn wired to the front pickup with the light. Sound like it might be in the transformer as well. When the 2353 AA set was running years ago (Early 70’s) it was run with a ZW, however it is on the list of thing I need to repair. The 1033 was in a set that my Dad picked up as a second hand store. The voltage look good across the different post, but the whistle side may need a deeper look, and it seemed to cycle the e-unit coil when applied.

Chances are the whistle rectifier disc in the 1033 transformer may need replacing.

Thanks Larry , I’ll look into that and see what I can figure out.
