    I bought a battery charger at a garage sale this past summer knowing that it wasnt working I took it apart and found that the dioeds mounted to a copper plate 2 were missing and 3 of them had the sodder broke free I tried to find these dioeds to replace them with no luck the # on the dioed is ARH027-8805 can some one tell me the sze of these dioeds are and where I can get them from and by reading some of the answers in other peoples posts I would like to have a studd on both ends of the dioeds and maybe the next size bigger in amp rating
    thanks for the help
    have a great day

    It might help if you posted photos of the charger and the diodes, if that is not too much trouble.

    It sounds like diodes so ancient that I forgot their name...selenium rectifiers?
    A photo would mean a lot, and read the specifications for us. The volts and amps it claims to produce.

    A lot of older battery chargers used car Altenator diodes that were press fit in rectifier assy or were soldered in place. I used to dismantle scraped car altenators for the diodes (free).
