Sega CD Mk2 Fuse Question.

[Siamey]

Ahoy! First post here, been lurking for a bit, this place is a godsend.

I have 2 segacd mk2s that dont do jack when i turn on the connected gen mk2 and i really want to bust out sonic cd and robo alteste.

SO i read that http://www.mrvfone.com.au/sega/fuse.htm Guide on fuse replacement.

What I've gathered is i need to replace it with a fuse that is rated 850mA (even thought the fuse that was in there was 2.5A ? whatever)

so im gonna got o radio shack and get some and then solder it in (i already clipped the old one off. Im assuming there is no right end to put in either way.

If anyone of this is gonna get me blown up or electricuted, please tell me.
Thanks!

Just don't solder it while it's plugged in and you should be fine.

As long as you use a fuse that is equal to or less than the original one, you shouldn't ruin the system either.

That is what the fuse it for.

Intersting though that they have you putting in a 850mA but it should work.

good luck,
Chesh

I just found this place also, and it is a godsend for sure.

Um,if i remember correctly,the Sega CD both models use the original MK-1601 9V 1.2 Amp adapter,and inserting a fuse that can resist what 850mA is kind of well a bad idea,wont it blow it cause 1.2A is 1200mA. So yea,i think you need a better resistor unless u want to do all that sodering and blow the resistor again.

i think the reason the tutorial uses an 850mA fuse is because they are replacing it with an actual fuse and not a new fusible resistor.

if the new fuse blows you can just replace it with a higher fuse. As long as the fuse isn't higher than 2000mA as stated in the tutorial.

I noticed that with my Sega CD unit, had the fuse used in the guide. However, my mothers Sega CD did not have that type of fuse, and was a surface mount on the solder side of the PCB...

Does it matter that it is PAL (in the how-to), or does the power supply handle all of that for you?

okey dokey, ive got some 1A fuses and a fuse holder thing, lets see how this goes! :)

DC is DC in the long run, so whatever the power supply "outputs" will generally be the same...
