How to Switch the Regulator Voltage

Remove any covers -- if there are any -- to expose the regulator's internal parts.

Unscrew any brackets that hold the capacitor to the framework of the regulator. The capacitor looks like a long, black cylinder. There should be two screws holding a U-shaped piece of thin metal over the capacitor. Use a screwdriver to remove the screws and metal bracket to free the capacitor.

Apply the hot tip of a soldering iron to the tips of two wire terminals on top of the capacitor. Do them one at a time until the solder melts and the wires come off the terminals.

Place the different voltage replacement capacitor in the same place where the first capacitor came off. It should be the same size. Screw it back on securely using the same bracket and screws from the original.

Place the wires on the terminals. Use the original capacitor markings to ensure that you get the wires on in the correct order. There will be markings on the terminals or just below the terminals to tell you which color wires connect to the correct terminals.

Apply the tip of a hot soldering iron to the tips of the wires and terminals together. Apply some fresh solder to the tip. When the solder melts and bonds the wires to the terminals the regulator voltage output has been changed.

Place any covers back onto the regulator in the same manner that they came off.
