Where can I buy a replacement F1 Resistor?

robotecha5 · Post by **robotecha5** » Sat Mar 18, 2006 5:27 pm

I have two Dreamcasts and the controllers stopped working in both of them on the same day!? seriosly what are the odds!? this is the first time i hve ever been truly dissapoited in the dreamcasts design, sigh. Anyway i found out i needed to replace the F1 resisitor. But does anyone now where i can actually buy one of these? and please dont say ebay.and i already tried Radioshack. THANKS

You can't get an exact replacement anywhere except scrounging.

Hey view the topic about dreamcast controller lead won't work ! Its exactly the same problem regards

You can replace it with a normal 10 Ohm resistor. Some people say not to use a 10 Ohm resistor, but I used one and I know several other people that have used them and they work fine.

yeah to some extend, but a fuse would do it better (I am from the people saying not to use a 10 ohms resistor

)
In fact it works, but did you test it with 4 pads with vmus/rumble packs Roofus ?

Nope, but I don't have that many pads, VMUs and rumble packs.

The 10 ohm resistor works but when you connect lots of peripherals not all of them will power on or they won't be as responsive. I even have a weird problem with my DC Mouse where it only moves horizontally when playing UT and not vertically (it's really annoying).

So if you only have few peripherals, it's ok to use a 10ohms resistor (in fact 1ohms 1/2W or 1W is probably a better choice).
Or else, use a fuse.

Or just buy another controller board.

Tank you I thought i needed a 10ohms resisitor but.
WHERE CAN I BUY ONE????????
Thank you.

Ironically, I think fatheapi might have some. PM him.

I'd say 1A fast fuse will be ok.

Thats because the original part was not a resistor. every time i see this i wonder why people use resistors as a replacement. the original part will have next to no resistance, and that would be why using a resistor will not supply enough power to power up all devces.
i am with semicolo on this , but i would prob use less than 1A becuase even with all devices plugged in and rumble packs it will prob use less than 1A (i am just speculating, i have never tested the drain).
anyway , thats my view that i have never expresed before
i feel better now

oh , and the FUSE .. you can buy anywhere. hell , use fuse wire if you have to

I did it because I found this on GameFAQS back in the day. I suspect that's where it started.

I suggested 1A because an 1/4W 0,39ohms fusing resistor can handle 800mA continously and more for short periods.

So 800mA may be better, but I think that rumble packs can drain up to 250mA, so 4 controllers with vmu and rumble would probably blow it if used all at the same time.

hello!
I used a resistor for the F1. I think it's 5Ohms or something but I have problems using many controller with vmus and rumble packs. I like the idea with the fuse but I don't know how to put it in. Maybe someone who uses a fuse for F1 could send me a picture or something! that would be very kind!

I just ordered some 0,33ohms 1/3W fusing resistors to make some tests with these. They will blow in about a second if draining 4W, it means it can handle current peaks of about 3,5A for a second or more for shorter time, so I really don't know if a 1Amp fuse would be enough.

if you want to use a fuse, desolder f1 and solder two wires going to an 1Amp(if it blows try higher values) fast acting fuse.

I just bridged the points where the resistor was.
