I basically drew this schematic from an actual circuit board I am working with. this is only the top half of the circuit board, there is still another side that I will work on tonight. can you all please give me some insight as to what is going on here. I am fairly new to this stuff.
the chip at the bottom is an LM2902 (I just show the top half of the chip) pins 1 - 7.
I believe power comes into the board from the Red wire in the upper right. Power flows through to the V+ on the chip and to the coil on the relay. I'm not sure what the two capacitors do on the right side do.
Also I am not really clear what the transistors on the left are meant to do.
Again Irealize this is kind of hard with just the one side, but I want to understand a litle more as I proceeed.
If anything ook wierd, please let me know. this took a long time for me to do and was quite tedious. thanks.
