Okay guys, I know I don't know what I am doing but I am trying to test a hockey puck SCR. I have a flashlight taken apart. I have the neg from battery going to negative of the light. I have the red wire from scr going to the pos of the light. I have the positve of battery going to the plate connected to the anode of the scr. I then take the white wire of the scr and touch it to the anode and the light lites up. I take it off and it goes off. This isn't the way I seen the test done online, but I couldn't get the light to do anything that way. I have several SCRs that I know some are good and some are bad. Also putting pressure on them doesn't seem to make a difference.
