Help Silicon Rectifier

Do you know the make and model of the charger?

Only 1 transformer wire goes to the diode, the other elsewhere probably an output terminal.

longer visible on installed parts. Is it safe to assume that the wires fr om the transformer secondary lead to the Anode and the body of the "button style" (cathode) is pressed into the aluminum plate?

The couple I putzed around with had two rectifiers. If there's another, ch eck that. In any case, the cathode should go towards the positive lead.

Mike, the model is a Schauer CR612

2 button diodes. Case bonded to copper plate, lead goes to xformer. On replacement diode (1N1190A) case is cathode.

Reilly, both diodes have a removable lead going to the xformer. The bodies are press fit into a copper plate. Do I simply unplug and check for current direction with ohmeter?

can you not work it out by following wires & using a multimeter? Old charge rs are exceedingly simple.

Just put it in, and then load the charger with a 12 volt headlight. Then check polarity, and flip the rectifier connections if the polarity is wrong.

Thanks all !!! Problem solved. Disconnected good diode from circuit, tested and determined that the anode is connected to the transformer and the cathode is pressed on to the metal plate. Will order the 1N1190A stud bolt replacement. Inexpensive, probabl y less than the shipping cost. Thanks again !

Just make sure the diode you get is polarized the same. IIRC, those stud r ectifiers were available with reverse polarity if ordered that way. Who kn ows if any of those made their way to the secondary parts market.

In future you should keep at least 1 high current smpsu in your junk to get high i diodes from

In the UK, we have discount stores like Aldi & Lidl that do time limited offers, battery chargers come around from time to time and sometimes they're

6V capable.

The David Silver Honda parts specialist allegedly has 6V capable Honda branded Optimate chargers - but never on any of the occasions I tried to order one.

Sounds like a half wave rectifier, there would be 3 wires from the tranny. If the diodes are the same you would need to make sure they were the same polarity as the previous diodes.
