Portable engine driven generator/battery charger

Here's my portable battery charger. It's a 5HP briggs directly coupled with a 12si 80 amp delco-remy 3 wire alternator. I done some wiring to make the alternator self-energize without changing the regulators. It's runs at 3600 rpm, but to get it to energize itself you have to rev the engine above 3600 rpm. Just a quick rev will do it.

Nice job! You can probablty do some light welding with that as well.

I'd have to make some other modifications to do that, 13.8 - 14v really isn't enough to keep an arc, but that was another project I was going to do was to make a small welder from an alternator and since I have a large welder on the truck, really haven't had the need for it.

Put an inverter on it and see what kind of usable power you can get out of it! Using a direct drive like I did too!! Slick! :-)

how did you wire it

that's a great idea with the direct drive system! lets see more of your work.

throw a power inverter on it, and you could power a tv.....
