I've been at this for a while now and cannot seem to figure it out.
With reference to the attached LTSpice cct. As it is, it works and both comparator switches. However, with R7 replaced with a short, comparator U2 does not switch. As you can see from the schematic, it's set to 1μΩ (effectively, a short?).
Any help is greatly appreciated. Thanks.
