The conundrum lies in your assumptions. You are assuming that if the field circuit breaker pops something must be wrong with the alternator system. Not necessarily the case. I'll leave it to others with more understanding of such things to elaborate.

I have been reading with interest your monographs on fuses and circuit breakers. I had always thought that CBs were "modern" and fuses were "old school".

So this brings me to an alternator wiring question. Keep in mind this is based on the Z12 architecture with an electrically dependent engine - EFI/EI.

The questions is: why would I use a CB on the primary and backup alternator field circuits?

My rational for thing this is, if the alternator field circuit pops, something is wrong, likely with the alternator. With the Z12 architecture, the backup alternator should immediately come on line and keep me, the electro-goodies and the engine happy. Why would I ever want to push that breaker back in?.

If the backup alternator field CB then also pops, I would then think that something is very seriously amiss. Again, why would I ever want to reset that breaker.

In theory I would still have the battery to get me *somewhere* safely albeit with urgency.

Inquiring minds need to know.

Cheers

Les

PS: The above assumes that my post start checks confirms normal operation of both alternators.
