Hi everyone, I recently picked up an LW transformer and need to replace the whistle rectifier. I am ordering a 10A10 silicone diode axial type. From what I can see there are two wires on the old rectifier, one on each side from it mounted on the bracket. So the first question is, will I use these for the new silicone diode as mentioned in an earlier post, opposite Lionel's schematic of diode direction? Now the second question is if I ordered a stud diode, how would that connect, wire wise?
I don't know my way around inside a KW, but I can tell you that a stud diode usually has a picture of the schematic symbol printed on it, like this one:
On this diode, the body is the cathode, corresponding to the ring on a lead-mounted diode, and the solder terminal is the anode. The diodes on the old Lionel schematics are indeed shown backwards.
(It's "silicon", the element, not "silicone", which is a kind of silicon chemical compound.)
