Flyback And In Circuit Transistor Tester

By on May 26, 2009

I got and email not long ago from my ERG member telling me that he was fixing an in-circuit transistor tester and building a flyback tester. I told him that once done he could send the photos to me so that i could post to this blog and let you see. Here is the email :

Good morning.This is the picture of the tester i have successfully built. and it can test good to bad component.Thank you sir for all your help. in circuit tester i used a double pole double throw switch. and it can test a shorted diode,open diode,shorted transistor and it can identify if it’s npn or pnp transistor.thank you sir again and God bless you more.

also flyback tester can test smps transformer primary,b+ coil, primary of flyback,even shorted diode and transistor,str ic can be tested using dicksmith flyback tester.

God bless us,
Zed

I guess he is still finding the right casing to put in the In circuit transistor tester. He had tested it and found to be good in checking diode and transistors. And here are the photos:

    I have been loving my new Blue Ring Tester...I have been using it alot and also playing with it to see what other components you can use it to test, and found it can test electric motors...the brushless dc type motors in dvd/cd players for instance should light up all LEDs when good.........

    EDIT:

    I meant you can test the PM motors but not the brushless......
