Re: (ET) Fuel Gauge - Blown Resistor




Off hand I'd say that carbon film, metal or wire wound will work just fine in this application. About wattage, if it's about 3/8 to 1/2 long and perhaps 1/8" in dia, use a 1/4 or 1/2 Watt resistor...

Does it matter what kind of resistor the replacement is? The original looks like a carbon composition, but can i use a carbon film, metal or wire wound? Any idea on the wattage of the original?

Anybody know what the proper replacement is? Seems to be a carbon composition resistor with orange-black-red-gold bands. I used an online identification tool and it tells me it is a 3000 ohm +/- 5%. Is this correct?
