...or...go with a single high output. You can get alts up to about 300+ amps. Mine is 250. Most are built for EMS and other service type vehicles. Might even be cheaper since they usually use the original mount/bracket.

I was hopping to get right around 300 amps but thuy only make a 240 one and it's 500 they also make a 400 amp on but it's like 1400 way to much.. cheap Asian! Lol I was hoping they make a kit for dual atl.. I think I see them on RVs but I don't know.

Hey NguyenBus,

Did you ever find an answer to this?

I would like to add a 2nd alternator to my Bluebird with an 8.3. I will be running a 24v house battery bank and want an alternator dedicated to charging the house battery bank.

Thanks.

S.

Nah. I put a 260 amp alternator in my carpenter 5.9 cummins. I can charge my huge solar bank rolling and run my air conditioner at idle.

Military runs 24V alternators on the cummins 8.3 for the M939 series 5-tons. Very mechanical everything, 1991.

Might be worth a look?
