Dear Mike,
Well noted.
We will do insulation test on the main rotor also, especially PI to ensure the condition based on insulation class. CMIIW.
Thank you.

Dear Mike and Bill,
Thank you for your respond.
Actually, we have not any testing yet after replace suppressor and rewinding the rotor exciter.
As both of you mentioned, before the alternator put back in service, we need to do as follows:
1. Flash the exciter to ensure exciter has enough...

Dear Bill.
Appreciate with your respond.
You are correct that the connection from rotating rectifier is not our issue as we didn't disassemble the connection of the rotating rectifier. We disconnected two leads of the main field from (-) and (+) terminal of the rotating rectifier, but...
Dear All,
Attached is the lead that we discuss it...whether it may be connected to rotating rectifier with consider polarity or not.
Thank you.

Dear Bill,
Well noted.
From your explanation, I assume that we can connect both leads to rotating rectifier terminals (-) and (+) with no risk i.e. burns exciter, suppressor diode or rotating rectifier. And if wrong connection only has consequences the output voltage will no build up. Correct...
Dear Bill,
Our AVR type is Marelli M40FA640A/A “MARK I”.
