If the engine was equipped with a generator to charge the battery, it will charge the battery, given enough time. Most generators that have electric start will have a generator but I have seen one that did not (I think it was an 8hp, larger ones are more likely to have it). If you trace the wiring from the battery, you will see that the heavy Pos cable will go to the solenoid (a big relay) and from there will be a couple of smaller wires that go to the key or start button. If you see additional wiring going to a metal box (often with cooling fins), this is probably the charging regulator so you could conclude that it will charge the battery. If you have a voltmeter, connect it across the battery (without the battery charger) and measure the voltage. Start the engine and check the voltage again. If it is higher, this indicates that the engine is charging the battery. Ideally, it would be about 14 volts (at least 13.5) which will charge the battery. If it is under 13 volts and does not climb up from there, it is probably not charging (or is charging very very slowly).<a href="http://www.resumebutler.com/Job%20Search%20Guides.htm"> TechnoStuff</a> This depends on the engine.

You have to find out why the battery went dead in the first place. A lot of people don't know that you have to polarize the voltage regulator when one install a new generator. I remember it's something like, using a jumper wire, touch(connect) 'A' with one end of the wire and then touch 'B' with the other end. That's it.<a href="http://www.jewelrymakingidea.com/jewelry-making-tool.htm"> ahpolkguy</a> Yes, the generator work similar to an alternator that it charges the battery directly.
