Merry Go Round not goin round!

phil kloppphil kloppOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

I bought a neat Merry Go Round at Home Depot that is a nice O Gauge size and operates well on three AA batteries (4.5 volts DC) and planned to change the power supply to a DC transformer.  But the accessory does not operate on 4.5 VDC coming from  a DC power pack set to 4.5 volts, or  two different  wall packs that put out voltages close to 4.5.  This accessory has two small motors, flashing LED's and music playing.   I have simply replaced the two wires going to the board that controls these functions from the battery pack to my Transformer DC outputs being aware of polarity.  Do batteries put out a slightly different DC than transformers?  I have often done this sort off thing before!!    Phil

I was able to solve my  problem by doing some research on Google.  DC power from a battery is regulated and that from the transformers I was trying to replace batteries with is apparently unregulated.  I have numerous Lemax carnival rides on my layout that use 4.5 volts DC power supplies that plug into home outlets.  I found that these work fine in powering  my rides!  The DC voltage differs from that which I was trying before!  

If any of you are looking for inexpensive  additions to a carnival or circus, the merry go round and tilt a whirl rides are still available at home depot for about $25 each with the Christmas items under the heading Home Accents.  You can see them online.  If you want to replace battery operation, the Lemax power supplies work!!!!!  Phil
