Forgot to mention, I did test wires on the fuse box but may have tested the wrong ones. Are these the wires you were talking about? If so I tested the one on the left and confirmed +12, but just noticed the one on the right in the picture so need to do that later tonight.
Fuse Box
Sorry, I'll try to clarify. I did originally bridge with a paper clip, but it didn't work. So I used a live wire (that used to be going to the grip heaters, but had to cut) and connected it directly into the other side of the thermo switch sensor connector as shown in the picture.
Also I'm not low on coolant just worried it isn't circulating. I'll try to test with boiling water next week, but I don't think I'll have time to do that tonight or over the weekend
Edit: Just noticed the image above for the visual is broken, fixing it now
