I have a few diodes that look like the blocking diodes you have in your store, only they have two small wires coming out of them, a red and a white ones, they came out of a old chloride charger,i stripped, Are they usable as blocking diodes? ps this is my first post on this site and i thank you in advance windchain
Hook them up to a 12 volt battery. And see if electricity flow through one end but not the other. If it does, then it is a diode. But I have no idea how you will be able to determine the amp rating of it.
cheers for reply,can they also be tested with a multi meter set on continiuty :?: found out that the ones with small wires coming out are thyristor diodes are these any use in a wind or solar system :?: ,power to the people windchain (at the btm of)
Yes you can check direction of current flow with a continuity tester. If the battery voltage is high enough. Thyristor diodes can not be used as blocking diodes. They are bi-directional and conduct either way at a set voltage.
