Great tutorial, already like comment subscribe.
I'm from Indonesia, I have a problem with the SMPS on the "ANJING" brand battery charger made in China using IC UC3842B on leg 7 (imput) with a voltage of 12 - 14 VDC, on leg 6 (output) there is a pulsating voltage of 0,5 - 1.5 VDC which goes to the MOSFET gate 7N65, on the drain leg the voltage is 210 vdc connected to the transformer leg, primary Elko voltage 320vdc, output 0 vdc, where do you think the problem is sir? I removed and checked several important components in the primary and secondary which had normal values...
In this conditions, is the UC3842B still normal or is there a problem? Thank You
