No reading on aux output. There is bell output though. So Tried pir on bell output and that works; however, fault still showing. If that makes any sense?

What rated fuse did you put in, 1A? Is it still intact or has that blown without you realising.
New pir wired up correctly?

Remove all pir aux wiring from pcb terminals and then take voltage reading without any devices connected.
