google translate: Hello everyone, have a good afternoon, I have a PROBLEM with my BROTHER sewing machine, I don't know how to connect a new switch with 3 inputs, (the original was 2 inputs) and I haven't been able to connect the connection of the motor with the lamp, I don't know if the motherboard was damaged
Welcome! Sounds like you've gotten the wrong part? I hope someone familiar with Brother machines will respond.
