Well it works but it wasnt as easy as I thought it would be.
Putting in the bridge was the easy part. I still had to find a
place for another filter cap and a choke. The caps werent too
much of a problem. I removed the origonal one and was able
to fit 2new smaller ones in their place. Since I was going to
drawing a lot less current than the PS was designed I
figured I could use smaller caps. I still havent settled on
where to place the choke. Its just hanging out the side
for now. I will eventually try some fast recovery diodes but
since the power supply origonally use stardard recovery
diodes that is what I will use for now. The heat sink the
diodes are mounted on get fairly warm, maybe fast ones
will help this.

Trying to figure this one out, The choke has two small wires
going back to the circuit board to a potentiometer and some
unidentifyable ICs. The pot is sealed with RTV. I am guessing
this is for overcurrent sensing. If I could verify this I would like
to set it to activate at about 10 amps.
