They are generally limited to about 30 mA, and not usually lethal. I
speak from one who has gotten "bitten" a few times. But they sure as
hell hurt!

If you are not familiar with the difference between series and

neon sign transformer!
Although, it is designed to be current limited,
so it *MIGHT* not kill you...

Last time I dead shorted something was maybe 15 years ago when I was
installing a new elec box behind my stove. That was a stupid thing to
do too. Then I kept on resetting the circuit breaker until I broke
that! I finally called the electrician to come out and tell me where
I went wrong (and I don't mean in my childhood). Sometimes my brain
just goes on vacation, I have no excuse.
I replaced the fuse and my meter works again. That's good- I guess I
quit while I was not too far behind, I didn't fry the whole unit. I
am glad I asked.
The wall wart says it is a class 2 power supply, input 120V AC 60hz
20 w, output 24V DC 500mA. I did not realize there was a difference
in those small units used to power all kinds of gadgets around the
house. I have not looked at them closely. I thought transformers were
more for high voltage applications, like neon signage and such. I do
have one of those too, but they scare me.
My regular 3 battery setup works fine. I was trying to see where to
set the potentiometer to keep the current controlled with an AC to DC
power supply. I just looked at my meter, and it says right on it the
max for that setting is 400mA. Darn it. If I hook it up to the
other lead, it will measure up to 10A, so I guess that is the way to
go, then when I get the pot. set, so the current is low, maybe then I
can move the lead to the other side.
