Adding charging system to honda GX390 engine
I would like to add a charging system to my 13hp Honda GX390 engine. It is trailer mounted for a power washing rig. I would like to add some work lights, and an electric jack and a 12v motor/ignitor for the hot water setup. I know I cant use it all at once and thats fine, but itd be better than having to be plugged into the truck all the time for that stuff to work.
What do I need to add this system to a non-electric start engine. It needs to be the biggest charging system they make for this engine. 16 amps or so?
