It is impossible to have fuse with 0 Ohms reading and have 12.85VDC on one end and 6.5V on the other end of the fuse. So Basically you have 6.35 DCV drops on 0 Ohm! Got to be measurement error.
What scale are you using in Ohm mode?

i never thought of it that way budm so must be a error in measurements as if tcon/panel was loading the 12v supply down it would be the same both sides of the fuse

That much Voltage drop between the two legs of the fuse means the fuse has quite a resistance to it. Current flows through 0 Ohms have no Voltage drops on 0 Ohms.
Basically the Voltage should the same on both ends of the fuse.
If he uses Ohm meter in K Ohm range or higher then the meter will not have the resolution to show low resistance. Try measuring 10 Ohms resistor on K or M Ohm scale and see what you have.
When you have resistance in the path of the current flow you will have Voltage drops on that resistance.
