It got an alternator on it and just ran lights at mates . He also charged batteries with it.........Not sure what else..
Don't know about regulator.. ?
He thought the other 5 HP on the firefighter was stuffed and was going me to just put this one on the firefighter....
He is puting big drums on a old 4X4 and trailer with firepump mounted, to be like a fire engine on his property.
I will have to get some pics as I have never seen the setup....
