It states in the R22 POH that in the event of the Alternator warning light coming on the correct sequence of actions is to:
Turn off all non essential electrical equipment
switch Alt off and back on after 1 second to reset the overvoltage relay

If the light stays on then land as soon as practical.

I have just been shown that the examiner for the CPL will want to see it in this order:
1. Alt off then back on after 1 second
2. If still lit , pull Alt breaker
3, turn off all non essential electrics including Gyros and transponder

Has any one else been asked to deviate from the POH? I'm curious.

If you follow the POH, then nobody can ever hang you out to dry.
If an examiner prefers a different way, then they will say later "why don't you think about doing it this way because...."
If you do it a different way, and the examiner doesn't agree, AND/OR especially if you can't back up your reasons, you fail!

What he said!

Always follow procedures identified in the RFM/POH. Poor knowledge of emergency procedures is the quickest way to fail a skill test. Comply with the RFM and any UK CAA amendments to it and you cannot be faulted. The examiner may give you suggestions from experience but alway seek clarification as to why.
