Using the wiring diagram identify both voltage regulators that resemble the one that was built in 4824
Pin 1 and 2 input U2 7805 pin 14 VDD
U1 7805 IC chip MCP2505 -14 pin
Using the wiring diagram follow one circuit from input to the output.
Input pin 4 and 5 (CAN-H CAN-L) IC UC535ON Input pin 7 and 8 pin out 1 and 4 goes to ICMCP2505 Input pin 13 and 12 pin out 1 goes to IC2 then transistor U3 then output connector 1
