Good Day To All!
I have a leaf blowing tool & its circuit board burned after about 3 decades of use. It has a 120 volt brush type DC motor. The speed control with which the user interacts is a variable resistor.
For the education I'll gain, I'd like to try to repair the machine.
While studying what is left of the circuit board, I drew what I believe is the correct wiring, but something does not look correct. I can't put my finger on what is wrong- if anything. I am not very familiar with quadracs, so perhaps that is the source of my confusion.
Attached are two sketches. One is wiring with the components laid out in the arrangement they are found on the board and the other drawing shows where I think the the circuit traces should be reconstructed behind the components. (Some traces are still present.)
Do you all mind to look at the drawings and tell me where I went wrong (if I went wrong) while trying to determine the correct wiring for this control board?
I sure appreciate the education!
Enjoy Today!
