Dual alternators
Has anyone done it? Can it be done?
I was thinking about getting an extra battery to run all my accessories off and was wondering if there was anyway to hook up an extra alternator to keep the battery charged.

What you need is 2 batteries, and an isolation kit. Both batteries will charge together, but you can drain one while the other one remains at full charge.

With all the electronics in the new vehicles today, Don't ever try and connect 2 batteries in series, which will give you 24V!
