[Shop-talk] alt or battery?

[Karl Vacek]

That's the old Delco Eye.  It's basically a hydrometer.  I've never seen a
truly bad battery where the eye was green, though a good battery might not
have a green eye.  I assume it's a malfunction in the hydrometer - maybe the
float sticking?  I suppose it could stick in the "good" position, but I've
never seen one do that.

This is a water level and charge indicator: green is charged, black is low
or discharged and clear is low water.
