Good evening, all!

Anyone installed a high output alternator on their ride? I run a farm and my mobile power needs aren’t met by my truck (maybe I could bring a gas generator with me, but that’s no fun). If you’ve installed a high output alternator (117 is stock and I want to go up to 320a), what modifications did you make? What lessons did you learn?
Power will go to a large inverter and from there to machinery.
To the mods: if this is in the wrong place, I apologize. Please move it if you feel it’s necessary.
Thanks!

 

The stock wiring is not going to work for that kind of amperage. I would suggest running two batteries and run new wiring for the amount of amps you will be working with. The stock fuse you can't go past a certain amperage(They don't make that style fuse in a larger amperage) I don't recall what it is but believe it's around 200A. So a upgraded fuse holder should be used also.

 

There was a factory dual alternator option. I have never seen one but I'm sure it could be done.

 

Didn't you have to give up A/C for that though?

 

I suppose that is another option, But would still need to run wiring/regulator for the second alternator.

Idk, my v10 has the spot for it above the air pump. I am not sure how it was handled on the cummins and v8.

 

The Premier Power Welder uses a 200 amp alternator. Need a welder? Just showing the 200 amp runs the welder with no problems. I was pushing 2000 watts RMS with the stock alternator when I had my 04 Corvette.
