Issue with power fuse

Hi there, bit of an odd one. Perhaps someone with a bit more electronics background could advise what the issue is here.

Issue: PSP doesn't power on. Charges fine.

On investigating the issue I checked the power fuse (Marked TB) with a multimeter to see if that was the issue. The fuse showed continuity so assumed it was fine.

Then by accident I checked the fuse again while a battery was connected and as I test the fuse with the multimeter the PSP powers on.

Is the fuse the issue? Seems when I bridge it that it powers on automatically, but why if the fuse is giving me audible continuity when I check it?

Also when I set the multimeter to ohms to check the fuse it shows as 0.00 as it should.

Found the issue, the ribbon cable between the power switch and the mainboard was faulty. When I was bridging the fuse it was somehow triggering the power on sequence bypassing the switch.

Swapped the ribbon cable with one from another faulty console and worked perfectly.
