need help with identifying fried resistor
« on: February 14, 2015, 10:28:17 am »
Hi!
I tried to replace the batteries in my Remington shaver mb42c, but I switched the power connectors resulting in a fried resistor.

do you have any idea what the resistor could be?

Not sure what the first photo is supposed to show?
The photo of the resistor shows that it is too "fried" to be able to reliably read the color bands.
Have you tried actually measuring it?

Hello Richard,
thank you for your reply.

I'm not having messured it yet, because i dont own a multimeter. I'm going to order an UT61C (http://uni-trend.com/UT61C.html).

Is there anything I can do now, without measuring? I could try drawing the circuit board.

It would be instructive if you could trace out the circuit. If the resistor is shorted or open, and the colors are toasted, it would help to see the actual circuit to derive what the resistor value might have been.

The only way, unless you haver another equal shaver to see what value the resistor got, is to draw your schematic. Resistors go open or get higher resistance, never shorted.

 Too soon to worry about the size of the resistors. Resistors don't fail by themselves, rather they fail because of some other failure that allowed too much current to flow through it. So more troubleshooting is needed to determine how many parts you might require including the poor resistor that gave it's life. Change the resistor first and it will just burn up that one.

Sure, you could grow a beard.  ;)

There's some videos of people trying to fix Remingtons - some are different models than yours but if you look long enough you might be able to see a closeup of your model in one of the videos and see what the resistor value is supposed to be -

I told my friends I could teach them to be funny, but they all just laughed at me.

Seem to be 10 ohms. What First band looks like is tarnished brown, second and third bands look to be black and 4th band is gold.
