F404 a 32 Volt 3.15 Amp fuse open located on the DPS boards A-2195-346-A and A-2094-368-A. After further checking there was a short on the other side of the fuse and of course that was the reason the fuse opened. Decided to remove and check the few capacitors after the fuse but all were good then removed the small regulator IC 408 the short went way. The part number for the ic is TPS54334DDAR and is available from DigiKey.
