<P>[quote user="tstage"]Anyone ever have a transformer go bad on them? I have a 3-month old Miniatronics 1.5VDC "wall-wart" transformer (that I use to run the exterior lighting on my layout) that is acting strange. The lights initially power up full but immediately reduce to about 1/2 power. Over a matter of a several minutes the lights get dimmer and dimmer till they are barely glowing. The outside of the transformer feels fairly warm to the touch but not hot. It just started tonight so I <I>really </I>haven't had a chance to test it out fully. Does this sound like a no-brainer problem with the transformer itself? Thanks.<BR><BR>Tom<BR>[/quote]</P> <P>Since your wall wart puts out DC (instead of AC); it is more than a transformer. It will have a few other components (capacitor, diodes, resistors, etc.); any of which could go bad. Without knowing your load (in amps) and if the load actually changed (increased) due to some layout malfunction; it is not possible to really tell where the problem lies. I would bet on a bad wall wart though.</P> <P> </P>
