Power Commander III: Powering up the PCIIIUSB

Follow

The Power Commander needs to be constantly powered in order to communicate fully with the computer. It should have a constant green light on. Make sure you have a fresh (above 8.5 volts) 9 volt battery if using the battery adapter. If using the bike's power, most bikes need to be running to provide the constant power needed rather than just turning on the key. Make sure the USB connector is fully seated into the Power Commander. If there is any silver showing on the connector, it is not completely plugged in. It is a tight snap-in fit connection.
