Flyback Diode Install Dummed Down

This section explains it in less words than dkwremotes.com/blog/flyback‍ ‍

Your goal is to install the flyback diode adapter inside your machine. It goes inline with the two wires coming out of the generator which have female and male spades.

The goal is to not install it backwards.

When you find the two wires coming out the generator, follow them to the spade connectors. This is where you will connect the flyback diode. If you keep following them, you will come to the back of the “4x3 connector”. Go the middle row. You see on the middle row, on the end, that is where one of your wires coming from the generator terminates. The black wire of the flyback diode connects to that one. Therefore, the blue wire on the adapter (marked dc neg) is the one that goes on the outer row one from the end.

Now that it is installed, your last step is to start the machine and try welding with the machine rheostat as per norm. If your machine runs a bead just like before, it is installed correctly.
