Lionel 1032 Transformer, Whistle Controller

[Stevereeno]

Hello there

Can someone tell me if the the copper oxide rectifier for a 1032 transformer when installing has the copper side facing out or the oxide side facing out?

 

Also what is the easiest way to remove the clip holding it in place?

How can one tell visually if the 1.5 ohm nichrome wire is bad and where do you buy a replacement? Mine has no apparent cracks and appears ok. How can it go bad?

 

Thanks

Steve,

If you are using the transformer only to blow postwar relay activated whistles, then the direction of installation is irrelevant, as the DC polarity generated does not affect the relay operation. Try and install it like the original, if possible. The installation of the rectifier is critical only with the newer electronic whistles/horns and bell functions, as their operation is DC polarity specific.

The easiest way to remove the clip is by slightly bending the tabs with a small needle nose pliers, and then sliding the clip off. Put the removed clip in between the jaws of a plier and gently squeeze it to return the clip to it's original state so that it will be tight on the stud. Use a small nutdriver to push the clip back on the stud with even pressure all around.

The nichrome wire rarely fails, and when it does, it will break. Repairing a broken nichrome wire by soldering is futile, as solder does not stick to nichrome. Replacement is the usual option. If your wire is intact, it is OK.

While on the subject, how do you wire a 167 into the layout circuit?

The resistor is supposed to be 1.5 ohms.  That may or may not be its exact resistance.  But, even if it is the intended value, that may not be enough to keep your whistle relay operated.  Measure its resistance.  If it is not quite 1.5 ohms, you may be able to fix things by adding some more resistance in series.  In fact, you may be able to improve operation by adding a little resistance even if it is already 1.5 ohms.

Thanks for all suggestions.

The wire was not the problem as i intalled a new one. You were right they rarely fail.

PROBLEM SOLVED

The rectifier was bad.

Thanks for all your help!
