Alternator info needed.

Does anybody know the output rating for a Briggs and Stratton Part # 793640 Alternator? I want to upgrade the headlight to LED. I asked Briggs support and this is part of the reply I got.

"The alternator on the engine will not support the additional items. We do not provide specs on the alternator either."

Kind of half baked reply to what should have been a very straight forward question in my opinion.

I plan on removing the existing light, and putting an LED unit in its place, but I want to get a light the right power rating. I also plan on adding the full wave bridge rectifier, and a couple of capacitors to smooth the DC.

Work fascinates me.

I found this information, I hope it helps. 2 to 4 amps unregulated DC.

Page number-3 seems to indicate 1.5 amps DC

Experience is something you don't get until just after you need it.

Appreciate the info. This looks like the info that Briggs does not publish... what?

According to Grunt's latest reply and good research you have 18 watts of supply which makes sense for a unit that have a halogen light as only option.
You can put a Led composed of 6 times 3 watts in total which would make a big difference from halogen. Good Luck

I wonder why on earth Briggs Tech support says they don't publish specs???? I guess the person answering either didn't know what I was talking about, or was just too busy to find the answer. Grunt, dunno exactly what you googled to get these links, but my attempts didn't return these results, unless maybe they were on google page 25 or something.

Thanks again, I have saved the info in my secret small engines folder

Your welcome skutflut. I store links I have seen over the years that are of interest in that same secret folder for future use. Sometimes I think I save to many, until someone needs it and I'm glad I kept them.
