That car battrry charger has been working ever since without any fault. The circuit is very simple yet highly efficient. I have charged totally dead batteries and i wouldnt change it for another car battery chatger. It is very important for me to find the said article. If i am so unfortunate i would apprrciate if you send ma a good circuit for a car battery charger which i can build cause i need one urgently. Tks for your kind interest.
Tks for all your help and interest.
Tks for tbr circuit also.
The most important issue of my charger is that it uses pulse width modulated voltage to trickle charge the battery when fully charged. A very important feature.
I ll start testing transistors, diodes triac to begin with.. See you guys. Tks
You are right. Problem is i need one now. That's why i'm trying to fix mine. Or else i have to buy one. Maybe if i find the appropriate circuit i'll build another one. At the moment i'm trying to service mine without a schematic. Thanks for everything.
Electronics Today International was a Canadian hobbyist publication, and won't be on that list. I had those issues from December 1979 to March 1985, gone since October 2015. None of my issues had PWM circuits in them, just simple elementary circuits.
