If it was intended as a fuse, it would be open not 4Ω.

Maybe not faulty??

 

It may not be I do not know

What problem are you trying to solve? What is going wrong?

No power on an AKAI speaker

 

No power on an AKAI speaker

Also it is connected to a Schottky Diode SS36

This i believe definitely faulty Reading on 0.16 in the forward condition and OL on reverse

Why I looking at the resistor also it looks not the best

what would you expect a schottky diode to read on resistance range ?

I think it is about 0.3 but not sure

1R3W would suggest that it's resistance is 1 ohm with a power dissipation rating of 3 watts. I agree with Yaakov. Measure it's resistance. The colour coding of the resistor looks like black, black, black, silver , black. This does not make sense so it i possible that the colours have changed if the resistor was running hot. (But if it was removed from the board in your photograph that does not look like it has been effected by heat from the resistor.)

Les.

yes was removed

 

yes was removed

meter reading 4.4 ohms

 

1R3W could also mean 1.3W.... albeit an odd way to do it. Can anybody tell what the color bands actually are, and what direction to read them in? One way sorta makes sense, the other doesn't....? Is that light-colored band white or silver?

I can understand the TP's confusion.

000 x 0.01 .... I'm leaning towards this being a *really low* value resistor, like 0.01 at 1% tolerance, and it's a 3W resistor....?

The image was taking under a microscope. The best you get the condition of it does not look good I think it is white

Diode mode, is unless its a real expensive meter, based on a standard silicon diode /gate drop, so the schotkey will be forward biased by most meters.

So one way you will get a drop, the other it will be open circuit, just as you have.

It's a 5 band resistor so if the colors were once brown-black-black-silver-gold it would be a 1Ω 5% resistor.

 

What is the device that the resistor was removed from and what were the fault symptoms that made you suspect the resistor ?
It would help if you can post a schematic of the area around the resistor.

I think you are correct going what is written on the board 1R3W -- 1 Ohm 3 Watts

AKAI speaker logic power Fault: No power I have no schematics for it I show an image of the resistor removed and from it you can see the text 1R3W on the board
