R236
Resistor value

(R236 / surface mount resistor )

Does anyone know the value of this component on the WP MOBO? It's right next to the IDE controller. My multimeter said .2 Ohms - can't be right...

thanks

You're right, it is a zero ohm. Seems like a strange circuit: there's a fuse (F3) and the zero ohm R236 in parallel? How's that supposed to work? Anyway, I could see one or the other, but not both? Oh well. This ends up being HDD VCC, which is the power supply for the Hard Disk, and is connected to pins 41 and 42 of the 44 pin pin CN12 connector.

thanks for the quick reply.

i broke mine - don't ask. hard drive won't spin up without it. since it is zero ohms, should i just "join" the solder points to fix?

Well, that might be ok.

However, what did you break? If you broke the resistor (R236), how did you do that?

If you broke the Fuse, how did you do that?

I would not recommend connecting a wire across there unless you knew what you were doing because you could fry your whole machine! If you blew R236 or the Fuse because you connected up a drive incorrectly, and then you simply wire across the pads of R236, and then you reapply power, you are just asking for something else to be blown (perhaps even cause a fire). Until you know "why" the resistor or fuse blew I would not simply wire across it. But if it worked at one time, and you 'knew' you screwed up and misconnected it, then yes you could do this, but at your own risk. Be careful.

I "physically" broke it - with a screwdriver trying to pry up the IDE cable... I’d replace it but it’s a bitch trying to find “zero ohm resistors” around here.

If you physically broke it then you shouldn't have a problem resoldering it. What I think is odd is that if the fuse and the resistor were in parallel, then as long as at least one is intact, shouldn't it still work? Oh well. Worst case scenerio, you fry your webplayer, your house burns down, it burns down your neightbors' houses, and they stone you to death with the gravel from the construction site down the street. But what are the odds of that? :)

What are you talking about? I haven’t gotten stoned with my neighbors since the 70’s

OK, so I took three thin copper wires from a speaker cable and twisted them together and tinned them. I then cut one heck-of-a small piece. I removed the remnants of the resistor and soldered the piece from point A to point B.

Couldn’t have done it without one of those alligator clip magnifying glass contraptions – or my butane soldering iron.

Works like a charm. The drive now spins up – and not a puff of bad smoke to be seen.

Thanks for the input.
