Flip the controller board on its underside so that the solder joints are exposed.

Remove the F1 fuse by using the soldering iron and desoldering wick.

The F1 fuse is clearly indicated on the topside of the controller board.

If the F1 through-hole of the circuit board is not visible, you may clean the it by removing the excess solder by using the soldering iron and desoldering wick.

If you are not using a fuse resistor, skip this step. Otherwise, continue.

Insert and solder the new fuse resistor to F1 socket.

The fuse resistor should sit on the topside of the board and the leads should be exposed on the underside. Orientation of the fuse resistor does not matter

The 10M 1/2 watt resistor in the picture is used to depict what a fuse resistor might look like.

If you have already used a fuse resistor to complete the previous step, you may omit this step.

Insert and solder the parallel 10 ohm 1/4 watt resistors to the F1 socket.

The resistors should be laid out on the top side of the circuit board and the leads should poke out from the underside. The orientation of the resistor does not matter.

The 1/4 watt resistors shown in the picture are used to depict what parallel resistors should look like.

Verify that the resistor(s) leads do not touch other components on the topside of the circuit board. Otherwise, a short circuit may occur when you power on the system.
