Thanx to everybody who replied (and so quickly too). I was pretty sure that the answer would be that there's a path that will allow the current to flow, but I just thought I'd ask as well. As for running a PIC from the Input Lines... Hmmmm.... That could be an interesting thing to remember for an application some time. myke >At 10:45 AM 2/20/97 EST, you wrote: >>The problem comes in when I turn off the Power and _MCLR to the PIC (Ground >>is still connected) - the LED lights!
