    Problem with my logic probe

    I want this to display low when the probe is floating. I thought it should looking at the design, but it displays high. It functions properly otherwise. Does anyone have any suggestions to fix this?

    I didn't read through all the posts, but you could try putting a kill switch to the battery in some discreat location, so even if they do try and hot wire the car there won't be an juice to get it going.
