PTO Driven Generator?

[71_Bronco 1,072]

Was just wondering if something like this is possible.

 

For instance, if you had a pull-start motor with no previsions for external power (like lights). Add some kind of generator driven by the output of the engine to generate power for lights.

 

Kind of like a starter-generator does, but not have the ability to act as a starter. Just the ability to out-put power to lights or other electrical accessories.

 

Maybe utilize some kind of small automotive alternator? With some form of regulator for the output?

You could use a Delco 10SI but it would have to feed a battery...

@Vurge did something like this. Not sure how the system was set up.

Maybe a ATV style alternator. Problem would be getting it to spin the correct way.

I have a trailer brake battery in one of my pull start only tractors.  I can run 2 LED headlights and a LED tail light for about 8 to 9hrs before I have to recharge the battery. May be a route for you to consider.

 

Battery.

here is a video of an installation. car type alternators have to turn in the correct direction for the coolingfan to work.

Sorry I've been away for a bit and just saw this thread!

 

I used a golf cart starter generator (SG) because most I found can be set up to run clockwise or counter clockwise.    

 

I am using mine on a Predator 212cc engine and it works well enough with a mechanical voltage regulator.  I have a thread and some pics of my 656 on this forum.  Another option I contemplated was installing just a generator- I have one from an old Ford tractor.  Those are cheaper than a SG. Setup would probably be similar. 

 

I have a small motorcycle battery (maybe 7 ah) on the 656 but the SG puts out enough amps that I can run my 1.8 gpm sprayer all day.  It pulls about 5 amps at my pressure setting. I think my SG maxes out at 15-20 amps so it's plenty of power.
