24 volt alternator ( auxiliary )

[HarryN]

I have been involved in some van projects where we added 24 and 48 volt alternators.

The 48 volt work, but it can be a lot more complex than 24 volt versions due to products availability.

Since my auxiliary battery pack will be 24 volt, gathering together info on what it takes to add on an after market alternator on the 25+ cummins / 3500.

The reason is that it is fairly easy to get 3 kW from a 24 volt alternator and much easier to move it around.

Right now just gathering information.

Thanks

This is a diagram that i was led to on another forum.

It shows 2 alternators in it, but I suspect that it is not a dual alternator setup, but instead the two alternator amp ratings that are options for this truck. Not sure.

TBD

Just adding another link for gathering info from a parts diagram.

I wish that these diagrams and part descriptions included a little more information, such as amp rating or something.

I have a 2024 Rebel 6.7 and it has 2 alternators. It was an option. Now I am trying to figure out how to harness that DC power for my RV trailer. What I mean is the wire with constant power on the 7 pin trailer connecter is maybe a 12 gauge which would limit the current going to the trailer to about 20 amps.
