Hi all,

I have a photo below of the resistor im trying to read.
DSC_0001.jpg


I have determined via a color chart the following

yellow - 4
violet - 7
silver - x 0.01
bronze - 1%?

this would give me a resistance value of .47
I just got a fluke multimeter and i turned it to the ohms feature, the one that looks like an arch\horseshoe. My meter is auto ranging.

So anyways, i touched the probs to the resistor and my fluke 179 says 5.300 k(ohms symbol here)

From what i gathered on the color chart, my multimeter should read around .47ohm If a resistor has failed would it read high like mine? I am new to all this and I am just looking for confirmation that what I have done is correct and that I am reading my multimeter properly

Thanks all for your help!!!

That resistor has a lot of oxidation on the leads. Make sure your meter is making contact with clean metal.

I put my probe tips onto the leads closer to the resistor housing. about where the leads start to bend, is that ok?

IMO that is an inductor/choke not a resistor...

0.47 uH +/-5% to be exact...

Im not sure exactly what that is, but how can i test it properly?

If you are getting a reading of 5.3K Ohm and it is infact an inductor it's 'probably' faulty... I say probably because as KJ6EAD pointed out it's pretty oxidated and a lack of proper contact could be causing such high resistance... If you are able to wiggle the multimeter leads (resulting in better contact) and get the Ohms to drop to a single digit value then it's likely OK...

there are little flat spots on the leads, also, i tested right were the leads bend to get my readings...

also im not sure what you mean about an inductor. I am very new so im not sure if maybe the color codes are different for an inductor etc?

p.s. this 'item' is out of a home stereo amplifier if that changes anything

Thanks :)
