why would I unplug it?? I just want to see if it works so I can buy an upgraded BV. my machine is working great with quarters. BV doesn't so im gonna order 10 photo optics just to use one. Does that makes sense?? better than buying a BV and have the problem be something else and then be stuck with 2 BV's, just looking for someone to tell me how to bypass it and make it send the signal thru. I guess I will buy a some new photo sensors and wait for them to come in from china. and cash can seats perfectly and moves lever across the photo optic slot.
