If you installed the OC and it's causing that issue then you did something wrong.On that 4N26 make sure you're wiring it up correctly..OC Pin - Controller1 - TP8, thru a 4.7ohm or so Resistor2 - Ground3 - Not Connected4 - To power LEDs or whatever5 - B+6 - Not Connected
Pin 4 of the OC (4N25) should be going to power your PIC (VCC) that way it has no power to it when the controller is turned off since the OC will be off.
Thanks RDC,my problem was I misunderstood the schematic and still had v+ from board to pic One other question is there another spot to get the switched 1.5v from, I have another cg board here and the contact is damaged on TP8.Thanks in advance
