yes hate is strong, but I really do hate the small blowers and AC DC transformers Gemmy uses, come on you can buy the same blower at your local computer shop for $2, and they would think you were crazy if you told them you were going to put it outside.

I really do not understand Gemmy, that do so good on so many things, I noticed one of our 2012 Globes had a 3 year warranty from Gemmy.  

needless to say I do not buy many of them especially for full price

But $1.00 eases he pain so I can tell if the transformer is bad or not.  this little DC test lamp is the best, just stick a probe in each hole of the transformer (with it plugged up of course) light its good, no light its bad  simple.  I did solder a small drill bit on the clip, just a little smaller than the hole.

 

any way here are a couple of pics

I share your feelings about those things. The problem is that they are not "transformers" anymore as both our governments have banned transformer type ac-dc power adapters as they are not energy efficient. Same as it is hard to find a 100 watt standard type incandescent light bulb anymore. I have seen these switching power supplies used with everything from pre-lit LED trees to little light-up villages and they are VERY prone to failure unlike the old transformer type "wall worts". They are definitely not 100% waterproof but are sealed just enough so that water gets inside them and won't dry up but instead shorts out the circuit board inside them, and corrodes the traces and the component leads causing premature failure. If the water ingress doesn't kill these little power supplies, they die of capacitor or semiconductor failure. It's really frustrating that you can pay good money for expensive inflatables or other lit up decorations and get such junky power supplies. Somebody should start selling replacements made with epoxy potted circuit boards and good quality components that will last more than one season and are actually waterproof.

I recently bought a pallet of "green laser lights" to resale, they have the same 'transformer" with them that goes with the small inflatables.  I paid $2.50 each for the lights, thinking about trashing the lase and selling the transformer, but then I know the failure rate would be high, but its going to be high with the lights too.  wish there was a good alternative.

My 4ft Santa inflatable stopped working in early December and I had to borrow the same ac-dc transformer from the other unused inflatable. The second 8ft Snowman inflatable stopped working after Christmas but I didn't have a backup (1.5a) transformer for it.

I recently bought both new 1a and 1.5a transformers from Yard Inflatables.

What if you separated the case AND filled it with semi conductor silicone or clear, fireplace sealant?

Now that's a neat idea, you might not even have to crack the case open if you could just drill a strategically placed hole or two and inject or pour in some sort of liquid silicone or epoxy potting compound in that would fill up the plastic box and set up and create a waterproof "brick".
