new engine question

on a briggs intek engine what is the difference between a 60 watt alternator and one that has a 3 amp alternator. can they both be used to run lights? do they need to be modded to run lights are they both ac or dc. I cant seem to get a solid answer thank you for any help on this..........also I added pics to my first post . have the 24" bucket and tractor completely taken apart cleaned, stripped and primed.

Amps times volts gives you watts. That said, 3 amps times 12 volts gives you 36 watts. 60 watts divided by 12 volts gives you 5 amps. The light you choose or handwarmers for either would have to be at or below the watts put out. I think

I didn't do the math but it looks correct.

You either want to add up the watts to watts or amps to amps to make sure that whatever you are running adds up to be less than what the system can produce at full throttle. It's rated at full throttle so don't be surprised if your light is dim or hand warmers aren't if you're running less throttle.

As for the AC or DC. It's likely AC as it's easier and cheaper. You need "stuff" to produce DC. Usually they only do DC if there is battery start or it comes with and LED light and if battery start then you not only have to convert to DC but you also have to regulate the DC 13-14 volts for charging the battery.

If you're going to go to LED lighting then you should install a rectifying circuit so you're feeding the LEDs DC.

The other thing is post the exact model, serial, family numbers of the engine and someone should be able to look it up and see what it came from the factory with.

Good reading and show and tell on how to convert AC to DC for LEDs - > https://www.snowblowerforum.com/forum...ed-lights.html

If it's AC output (most likley) you would need a rectifier bridge to convert to DC for use with LED's. Similar to this one that is water proof & vibration proof. 20 Amp is over kill especially for LED's. Poke around and find one that is rated higher than the lights if you don't want to spend $18.00.
