ru this is very noobie question, please accept my apologies in advance.

ru Could someone be kind enough to tell me how to check for resistor
ru functionality?


ru I pulled the resistor and theres no writting on it other than R10.

ru Its an inline resistor.

ru I think it is defective as it got overly warm.

ru please advise.


Hi, noobie! ;-)

If the resistor let the smoke out then it was overly warm. If it still
looks intact then it is likely still good. Resistance is easily
measured with a dmm's ohm-meter range. I'm curious what that resistor
was used for? Resistors with wire terminal don't often have writing on
them, just a colour code. Surface mount types sometimes have writing.
