Combining the output of two alternators
Combining the output of two alternators
(OP)
Hi,
What are the challenges of combining the output of two alternators, running at different speeds, to charge one 12V battery?
In particular, one or other alternator could be stationary while the other is rotating. I don't really see how this is different to a single alternator charging a battery, if the alternator is too slow or stationary the regulator diodes prevent current flowing back from the battery into the alternator. But I've learned to be wary of such simplistic observations...
Thanks, Ian

I wouldn't install it on a boat. There are other ways of getting a tach signal than from the alternator regulator circuit, and boats have enough single points of failure already.
