That's not true on the (pencil type) 617, the GP light will fail to light if two or more GPs are open. On the 616, the GP light will fail to light if one or more GPs are open. I've never had a 616 or 617 GP light blink to indicate a bad GP.
I agree that the GP resistance test will normally tell you if they are functioning correctly (but there are exceptions).
