Another thread on a broken ps7 fuse

[BigMichiel]

Hi again,

Let's cut to the point, shall we? I'm positive that my ps7 fuse is blown. And I'm not a tech skilled guy. So a couple of question's

1. I know that I can replace the fuse with a wire, but what kind of wire should I use for it? And what are the disadvantage of it?
2. Where can I get those fuses? (I live in the netherlands, and don't own a credit card)
3. On what setting should I set my multimeter to check out if it's broken or not? And what kind of values makes it clear that it isn't broken or that it is broken?

Thanks in advance

DON'T just bridge the fuse with wire! The fuse probably blew for a reason, and bridging it with wire will only cause something else to blow down the line (and probably something more serious than a fuse!).

Depending on what version your PS2 is, the PS7 fuse can vary - usually either a 0.7A or 2.0A fuse (available at any electronics store).

That should get ya started...

Thnx for the quick reply.

What's the diffrent between a 0.7a and a 2.0a fuse? Is one better than the other one, or if I use, say a 2.0a fuse, I have a better protection?

This will probably sound like a n00b question, but the thing is, I am a n00b about this sort things.

It's how much voltage (amps) that it'll take before the fuse blows. You'll want to replace it with the exact same type of fuse.

you also should be aware, that there are diferend kinds os fuses,
even if they look the same and show the same ampere.

there are super fast, fast, medium fast, slow (and maybe super slow) types.

which means, that a 2A super fast fuse will blow up first and the
2A super slow is last.

you will have the best protection with the super fast one, but in some cases
it isn't recommended to use them, because when you turn on a electric
device, all the capacitors and stuff are mostly empty.
therefore it takes some seconds (max. 5s) to (fill them up) and during that
time the curent consumtion of your device is much higher than normal.

Also, I've read someting about a SMF fuse. Do the new one has to be this kind of fuse, or can it be a other one?

[modicullus]

It can be either or. The one that are current on the mobo are SM (surface mount) fuses, but you can also use the ones that look like a normal resistor - just make sure you don't let the legs short on anything!

sorry, but i don't know what a smf fuse is (maybe it is a self healing fuse,
which are most common in new electronics).

but i know, that you don't really need it.
if you wanna chose the cheap way and you have some space left near the
place where the original fuse is, you also could solder a holder for common
glas fuses with some wires to it (but you must be sure, that this fat one doesn't create any shortcuts, maybe you could wrap it in isolating tape).
that way you can experiment around with it and try the fast one first.
those fuses are really cheap and you can get them everywhere.
but it must be the corect ampere type (0,7A, 2A or whatever).
and don't use a (super slow, your ps2 might start to smell...he he he).

P.s.:the fuse holder with the wires should be fixed somehow, don't let it loose
hang around on the wires and don't let the shild housing touch it!

I'll go to some electronica stores in the city tomorrow after school, see if I can find some fuses. If their cheap (I espect them to be cheap) I'll guess that I will take some more incase it happens again.

well the glas ones i mentioned are cheap, but they are aprox 2cm long
and you might need a holder for them (or you can solder the wires directly
on the fuse, but than it is hard to fix it somewhere).
check out your available space first.

P.s.:those holders are comon in many electronics, maybe you can demount
one from some old electro junk.
