Hi hive mind. I’m trying to fix a sewing machine power board and I’ve found a power resistor that’s blown. I have a circuit diagram (IMG_0056) and the resistor in question is R10 2.2ohm 3W. Firstly what is its function? Is it current limiting, voltage limiting or something else? IMG_0056, for illustration purposes only, shows the type of resistor in the circuit but at 47Kohm obviously I can’t use it. Can I use, nearest value wise, this resistor that I have got, in IMG_0058? What would it’s impact be on the circuit if I were to use it? |

I don't see the images attached (as your post was supposed to refer to them). Could you try reuploading them please? |
| Robert A:
Sorry about that, don’t know why it didn’t attach them. |

Is it possible to get the rest of the circuit diagram? It would be good to see what those power rails are powering. |
