Multi Purpose Power Supply

I needed something more than 12 volts at a reasonable power, and had a 12 volt 20 amp battery charger that I no longer use, so I stripped it down so I could use the transformer, I took all the laminations off, unwound the heavy coil, and rewound with 8 lengths of 24awg wire, I paired each of 2 windings to end up with 4 double wound windings of about 14 volts each.
All the windings come out to individual connections on the front panel, along with all connections from 2 bridge rectifiers, so now I can wire any in series or parallel for different voltages and currents, including the ability to have plus and minus supply..
This is the diagram so far
