Replacing Fuses

How would I check to see if a fuse is broken or not? My ps2 randomly died and I am leaning towards the fact that some of the fuses blew up. Also, could I just bridge the connection of one of the fuses once I have detected one?

Using ohms I presume, but what would a broken fuse return. 0 , 1, some random number?

Set it to continuity ("beep") mode. No continuity, no beep.

After testing I found two problems:

( notice - high res photos )

The first one blanked out completely, while the second one was iffy(probably how I was holding it)
I plan to order from digikey, so I could get an extra, but in the meantime can I just bridge the connections?

Also, do you have any idea what the fuses specs are? The writing on the PCB isn't very descriptive ( just says PS 1 , 2, 3 nearby the fuse)

THANKS

I wouldn't bridge the connectors. If the fuse blew, it's an indicator that something's wrong, and it was to save the circuitry. Bypassing the fuse could be like taking down a wall and end up *Can'tSayThisOnTV*ing up your PS2.

You could do it, but I wouldn't recommend it. It defeats the fuses' purpose.

Ok. Ill have a look at one of my other dead ps2s, see if there's a similar fuse on it to transfer over. How can I check if it is the exact same spec?

How does a mini fuse look like exactly ( I know how the bigger ones look - circular tubes ) ? The text on the mobo is too general for me to derive any useful information. The scans on the web of the ps2 fuses are low def.

They are usually just small black squares with solder on both ends. The fuses on most boards are marked with an f. Like f1 , f2 etc.
