I'm not familiar with the cockpit display in the 737, presumable its graphical rather than spell out "HIGH VIBS LEFT" ?
The VIB display (according to picture at Aviation Herald:
Incident: GoAir A320 at Delhi on Jun 21st 2017, bird strike, wrong engine shut down and restarted) looks like
0.0 — VIB N1 — 0.0
0.0 —
......N2 — 0.0
... and it
did occur to me that in a rush, or lacking experience with a VIB indication (or one's morning coffee), the brain could read
0.0 — VIB N1 — 3.6
as "(Engine) N(umber) 1, Vibration 3.6"
Not an excuse, possibly a reason.
