I have 2 alternators – although since I have 2 batteries and I’m heavy (the plane that is) – I’m considering taking one of the alternators out. I mounted the second alternator on the intake side just above where the water inlet is.  This picture isn’t very good – but you get the idea of where it is. It’s a small 6lb. Powermaster alternator.

It would seem that taking out one battery would get rid of more weight; unless you have some other reason for wanting to get rid of the second alternator. Although I’d say a battery is more reliable than an alternator.

 

I think two batteries and two alternators is redundant redundancy, and a weight penalty.  But that’s just me.
