Display issue

I have a tym t503 and if I hold the key to start position, my horn, blinkers and dials on panel work. As soon as it is in on position everything stops working. Any ideas?

Bad ignition switch?

Mis-wired fuse panel?

TYM did have some display issues. If I remember right they would just fade and stop working completely. I’m no professional, but usually issues like this is a ground or shorted wire issue.
