I have a nice heavy duty auto battery charger that was gifted to me. Someone had tried to repair it (remove parts) before I got it. The problem is that I can't find a schematic and the 4 missing parts c5,c7,t1,t2 didn't come with it. I was hoping that someone with more knowledge about circuit design than myself could help figure out what's missing. Thanks for your help.20210322_130437.jpg

Hi J,
My guess is, for T 1 and 2, the 3x PIN ones, the function selector and Volt selector switches. ( Or perhaps T = Temp sensors?)

EDIT: I've had second thoughts! Now T may = Power Transistors.

Show the rest of the Schematic.
Cheers, Camerart.
