Alternator meggering and AVR Card
Alternator meggering and AVR Card
(OP)
Hi,
I am new to alternators and AVR cards. I would like to know the reasons(and consequences) of isolating the AVR card before meggering the alternator.

After isolating AVR card during meggering, no more damages recorded .

The consequences will be destruction of delicate elements like chips and integrated circuits.

Thanks for the input. In fact the practice of isolation is followed by the engineers here. But in a case under emergency they somehow missed the step isolating the AVR card. BUT no damage occured to the AVR card.

I use the word may because of the many varied connections of both the power circuits and the sense circuits of AVRs that are in common use.
I'm glad to hear that no damage was done, but most of us don't take a chance. we disconnect the AVR before meggering.

RE: Alternator meggering and AVR Card
Sorry for the inevitable delay. Your input is commendable. I actually proposed to disconnect the stator feedback to AVR card and do the meggering again (with stator disconnected from the outgoing ckt). Now, with your input I am rethinking it.
Thanks and Regards
