[Sealtest]

I'm needing some help with this thing. I replaced all the caps (even tested them with another checker), and this unit is doing some odd things. After calibration it seems to test resistors just fine, but it refuses to test any caps. When testing caps the "eye" just always stays open no matter what.

Is there a common issue with these that cause this? I really would prefer to not take every part out of this thing.
