Hi Rob,

Bit hard to tell from that photo.  With power off and the machine unplugged from the wall, that jumpering plug can be simply unplugged and removed from the machine.

Being a young fit whipper snapper, if you look closely the numbers are actually molded onto the plastic so you can check it 100%.

If you're like me, a magnifying glass the size of the hubble telescope helps.

Thanks mate all good. Pin 1 is actually with tab on the bottom positioned at bottom right not left so jumper settings are ok. Helped me heaps mate thanks

So back to wondering why pcb is getting hot?
