Right off the top of my head. C1 installation is the problem. Bend the OUTER tabs upright, and twist them about 90deg. They CANNOT touch the chassis. This CAN is 1/2 of the voltage doubler and must be isolated from the chassis. The "GROUND LEAD" on C1 is actually an interconnect between C1 Negative and C2B Positive which is the ORANGE wire on the tab @ 9oclock. Disconnect and remove the BLACK LEAD at 6 oclock and bend the tabs up and twist. The Tabs bent over and the black "Ground Lead" are causing the short.
