Will l be able to tell the fuse has blown by just looking at it or not?
It's much easier with a multi meter cause it's hard to see a break by just looking.

+1. The only way to check a fuse properly is doing a continuity test with a DMM.
If you have Stern machines, you should be able to check the fuses by looking at the re LEDs on the board in the backbox as well. Just remove the translite and you will see if there are any LEDs not on (make sure the coin door is closed as well) and this should give you a pretty good idea if there are any dead fuses or not.
