strange Neon sign transformer

[Judges]

>>>>i need a single 3000 volts connection but my neon sign transformer has two 1500 volts connections,<<<<<<<

Your transformer has two 7500 connections,,,measured from terminal to case.
When you measure from terminal to terminal you will have 15,000 volts,,,,Do you understand me so far?

>>>>>i am a newbie, so i am confused,
can i get two high voltage
diodes and connect the two outputs to a single wire to get a single 3000 volts connection.<<<<
,,,,,,,,,, NO,,,,,,
>>>>>>>>>i want the other end to be ground that is why i am not connecting the two outputs across.<<<<<<<<

If you connect the two outputs together and plug it in you will KILL it.
>>>>can anyone help if the diode idea would work or not.

No Problem,,,,me and the big,Okie will help you.

If you connect two output wires from the same coil together, they present a dead short (0 Ohms) to the coil.  Very unsafe unless! you have a special grounded core transformer.  Neon sign transformers are sometimes made this way.

Judges is right.  That's an electrical short circuit and will certainly destroy the coil turns and may burn down your residence or workshop.

Sure, I don't mind helping a beginner.
