Tested all fuses. The ignition relay fuse reduces the drain. Tested ignition relay seems to be okay. Any ideas?

Good morning,
Did you measure current or voltage at the battery?
I attached a guide for you to view. It gives you the steps for tracking down a draw.

Thank you for your reply, new battery fully charged. Checked all fuses and relays have a draw between negative pole and negative cable. The only drop in drain is when I take out the ignition relay fuse. Although the relay clicks and has zero draw across terminals ohms.

Are you measuring amps or voltage?
The spec is 50 to 75 milliamps is normal.

Thank you for your reply. I think I have found the problem. I am getting an ac reading across the battery when running the engine so I think it must be a bad alternator diode.
