How do I identify a resistor ?
 

Fried a resistor in a gas gauge. It is orange with the black end, and seems to hae an 04 on it and an I T something under that. It's fried. I would take this to Radio Shack to match up, but those days are gone.

Any help would be appreciated. It seems a shame to waste an otherwise good gauge.

pic pls.

It would seem this is more likely a diode than a resistor. Pic would help as others have requested.

My money's on cap. 104 = .1 uF, black end is polarity..... ;)

Best picture I can muster.

That’s a diode.

Yes... Glass diode!

Easy fix.

Blew up when I cut it out. maybe a

IT?

It rolls around like that.

Yup, I lose.

physically broken?

1N4004 is popular diode. (is it N instead of k?)

And what is the idiot's guide ?

Yep, it blew up from a full reverse polarity episode. Shattered the glass.

2.29 on Ebay. Thanks guys.

I just checked my junk drawer. Sorry don't have any.

10 for $5 on amazon prime.

Just took a look. Found one in my spare parts bin - used, but it checks out okay with my meter. Send me a PM with your address and it can be on its way tmr if you want it.

Thanks Mark, I already ordered a few. Now I just have to be patient.

Do I need to use a heat sink on the wires while soldering ?

When I usually have a burnt up resistor it burns off the stripes and I have to find it on the schematics to see what the heck it was.

That does look more like a diode than a resistor though.

Solder carefully, they don't stand up well to excess heat. Use the bare minimum of time with the iron on the component, and use a heat sink.

Needle nose pliers with a rubber band to keep it shut will soak the heat. Between the solder joint and the diode.

Solder pencil, not a gun. ;)
