Hi folks

I have an old fast battery charger, well about 25 amps anyway, I replaced the selenium rectifier with a silicon bridge years ago, but I am now on my 6th at least. The slightest spark or overload seem to blow them up, one has just gone this morning and I only have one left. The rectifier is rated at 25 amps 1000 volts, is there anything I can do to protect it?

Thanks

Peter
