Got a battery charger. Puts out (or used to) 12 V or 6 V, and up to 50 volt
boost. Diodes no longer have continuity in either direction.
Are replacement diodes available? Or just easier to pitch it and buy another
<< They didn't seem to have any diodes with a high enough amperage. >>
Find a high output truck generator in a wrecking yard and salvage the diodes
from it. Parallel as many diodes as you need to get the ampereage you want.

Radio shack has some diodes that are high amp and may work depending
on the form factor. In fact, they even had the full wave bridge
rectifier that goes in my 6KW boat AC generator. It's worth a shot.
The Onan part for the gen was $45. It was about $3 at Radio Shack.
Sorry, had to beat my head on the computer. I just scrapped an alternator
which had good diodes. It had mechanical problems. I may also have a diode
bridge or two from awhile back.
I had a 10A Batt charger diodes blow when I tried to charge the batt
for a battery operated livestock fencer. I learned a hard lesson real
quickly, to never connect a batt charger to a fencer thats turned on.
The High voltage pulses worked backwards into the charger and knocked
out the diodes in a split second. (take this as a warning for other
Anyhow, there is a local motor rebuilder in town. He also rebuilds
car starters and alternators. Well, it turns out that alternator
diodes are basically the same thing. The ones I got from him were
well over rated for amperage for this 10A charger.
I think this is exactly what you need. Either find a local rebuilder,
try your auto parts store, or rip apart an old car alternator from
your local junk yard.
You might need to do a little mounting modification (I did). Be sure
to apply silicone grease for heat conduction (sold at Radio Shack).
Let us know how this works !!!!
