Testing Cathaodes

Ok Seriouslly Im stupid, I dont know how to make these light up before I install it. I wanted to test them to see if they work before I get them on, I tried the - and + batteries none of them seem to work. What can i do to make them work?

Help. (Im not a neon pro like u all are so yeah)

the cathodes plug into your transformer on the side which has 2 plugs, the power/switch plugs in on the other side which has 1 input and then you can touch the red wire to positive, and black wire to negative to see if they work, umm you may wanna make sure the switch is turned on

Before the switch, yellow is + and black is -

Don't get the polarity wrong. Make sure the switch is on.

Tried everything. Nothing

Is there like a little Battery or anything I can buy from radio shack or anything and see if it will work with that.

I took it to a friend earlier and one of the Transformer works for all the 4 Catharodes i got but the 2nd Transformer doesnt.

Use a cut off cig. adapter. That's what I use to test everything.

Ok seriously It wont light up at all when i have the switch postion on ON.

I tried the + and - on my car battery and tried the others they wont light up at all, this is making me mad. I know there gotta be a simple way to light it up like if u want one in your room and i dont know how they had it lighten up.

Ok I took the Pic from Vice's Old thread. I wanted to test it with that somthing like that with the power box he has or so.

What I think you might have done on the second transformer is blown it by reversing the polarity on it... I am pretty sure that would mess it up but I am not 100% sure.

If you hook it up just like you are hooking up the working one... and it doesn't work then that means it is bad.

Yikes.. Im gonna try to find a way to see if they work with the cig adapter.

I'll let u know if they work or not.

Phil, you're right even if you just reverse the polarity for a few seconds the invertor will fry itself. aka instantaneously dead.

sparks and smoke

learned that the hard way
