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 charger?

Yes, and yes. For parts I shop at
Thanks. Looks like a really great resource. They didn't seem to have any diodes with a high enough amperage.
40 amp 600v isn't enough?

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 farmers).
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 !!!!

I think you meant 50 "AMP" boost !!!!!
Try here:
Didn't see those. Do you have a part number for me?
You are right.
I have a farmer friend who used to use the boost setting for charging batteries. One time he wiggled a clamp, and blew up a battery. I've been calling it "12 volt blast" since then.

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.
It was on the 3rd page of diodes.

The term now in the vocabulary is D' oh. Also known as a "homer moment".
