Hi,
Ops diagram;
That diagram has those switches shorting the 12V supply to gnd when in the left position, don't use fritzy, I understand that they are not the switches that you are really using.
What switches are you using?
Please post a link to spec/data of the switches.
Can you post a picture of your switch please?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks.. Tom..
