Additional 12v alternator

[galaxie428]

Has anyone added a 12v alternator to your humvee with a 6.2 or 6.5? I be interested in learning more about your set up if so.

I have a 24 to 12 converter but I'm getting beyond what my 60 amp alternator can keep up with. I also got a heck of a deal on a 12v winch I'd like to add.

I'm thinking of adding a 3rd battery and moving all my 12v to it, letting the 12v alternator keep it charged.

I'd recommend a 200 AMP Dual Voltage Alternator be better as it would be able to maintain system load, and also provide a 12V output.
I work on rebuilding military alternators and starters and it sounds like you'd be at risk of blowing the 60 AMP alternator with too much load.

The cost to switch over is mainly the reason I haven't. The cost of the alternator alone is crazy and then all the pulleys and water pump I'd say you'd have well over $2k in it.

I read on here in a thread that the 12v output isn't much on the dual voltage alternator anyway so could that even keep me charged?

I'd think I could add an alternator for well under $500 with some fabrication of a mounting bracket.
