I've seen these that were so weak that no gun would reach cutoff and they'd all 3 read in the very low end of the "BAD" scale. As you can imagine, the picture wasn't too good on those really weak ones.

And, I think the reading on that B+ fuse is normal. I think those are of the slo-blo type and they will show some resistance.

And worst case, I'll try the restore functions on my tester if it gets bad. I don't even know how well this set will perform now.

Completely slipped my mind about that being a slo-blo fuse. I guess I just didn't think it would have been that much resistance. Well, looks like I may have another problem then. I'll look at it more tomorrow. Good news is it didn't blow my 4A line fuse.
