Audio Grade Fuse, Anyone?

I don't have a meter-I guess I can get one.But on my board the transformer and wiring is on the right.Below the fuse currently in place there is writing:Jp 03 on the right,Jp 04 on the left so I would think direction of the fuse should be pointed going right to left-do you think this is correct?

I didn't realise that Alternating Current travelled in only one direction! Kind of makes the direction of the fuse very important, if that is the case!

Dusted, I also thought the wiring in my Exemplar 3910 was obvious as the ac came into the board beside one of the snap-ins of the fuse holder. My meter proved this to be wrong. Meters are cheap at Radio Shack. Make sure the unit is unplugged and the fuse removed before testing.
