Thanks Bernard. This is a great tool. I coasted until the 3rd problem. It required real thinking so I just saved the site to my favorites. Reading your meter and knowing which settings to use for particular issues is so important.

But thinking through the sequences and applying likely logic is where the challenge awaits when you have a circuit board and 15 cube relays staring at you.
