This secondary power supply fuse is located on Millennium, Freedom, Lucey and Lenni machines manufactured in 2013 and later that have toggle switches on the handles. This small 2-amp power supply fuse is on the Power Supply Circuit Board. If your machine has no power, first check the Main Fuse located next to your on/off switch. If that is blown, use the 6.3 amp fuse (part #2089-03) for Millennium, Freedom and Lucey machines. For Lenni or George machines, the main fuse is 3.15 amp (part #2317-01). This part fits all generation models.
