Ok, I see the diagrams for the chip being installed. But alot of the wires are bare??? What if they hit eachother? will it short out the machine?? I've went ot my local Radio Shack, and purchased intercom wire, I strip the sheilding off the ends so the copper is showing. Is the type of wire ok for the job??? But my main question, is if the wires are bare, will it short out the machine??? Thanks again.
