Power feeding alarm warning light went off quickly (9)

I believe the answer is:

scarpered

I'm a little stuck... Click here to teach me more about this clue!

'went off quickly' is the definition.
I can't tell whether this defines the answer.

'power feeding alarm warning light' is the wordplay.
'power' becomes 'p' (symbol in physics).
'feeding' is an insertion indicator (one word is fed by another set of letters).
'alarm' becomes 'scare' (I've seen this in another clue).
'warning light' becomes 'red' (in traffic lights).
'p' going within 'scare' is 'scarpe'.
'scarpe'+'red'='SCARPERED'

Can you help me to learn more?

(Other definitions for scarpered that I've seen before include "Cleared off" , "escaped" , "ran away" , "Left" .)
