alternator???

[Franklin1283]

Hello,

I have a 5 hp briggs, and I was wanting to put some lights on it. Now, if I run an alternator, what type should I use, can I use one off of a riding mower? Do I need a pulley to run it, or can I just us a belt over the drive shaft? Also do I really need a battery if I don't have electric start? And If I do all this, will it decrease the power of the kart?

Thanks!

Do a search mate, this topic has been covered in detail before. I'm pretty sure there is a sticky under 'Engines & Clutches' section about adding a chevy alternator.

A conventional alternator off a car normally robs an engine of about 3-5hp. Most small industrial engines that have a battery use a charging coil.

This is kind of ghetto but they used to make lights for your bike and you would mount it and a roller would touch your tire and generate the electricity for the light. You could have it on or off and if you made a mount could you just roll it on your go-cart tires sidewall?

A lawnmower charging coil would not work simply because its built into the motor under the flywheel and it wont fit in a 5hp briggs. You can use a car battery and recharge it every so often.

or maybe a quad or dirt bike battery

Why not? If it is sourced from the same series of engine, it certainly will!

No. It's a bolt-on part. Is the ignition coil built-in?

and it wont fit in a 5hp briggs.

It will if the donor engine was a similar Briggs

This is the simplest solution. I did it for quite some time.

Find a 5hp pushmower with headlights and a charging coil for me, I wanna see.

You said it-

Besides- mower or not, if you source a charging coil from a SIMILAR ENOUGH engine, it can be made to happen.

Anyway, whatever. We are NOT turning this into a peeing match. To the OP- IF you can find an OEM 12v charging or lighting coil for yours or a very similar model, yes you can use it. You may have to swap flywheels depending on what you have/need.

FTR- While I am not the authority on Briggs equipment (or anything) I can tell you that Lawn Boy had an electric start model- just a simple example.

But they dont make a charging coil for a 5hp briggs and none that would come close to it. I wanna see this

Karl- If you read my comments CAREFULLY, you may notice that I did NOT say whether these parts were actually available. You may even notice I used the word "if" more than once. And, IF no such parts exist, then I guess the OP really is screwed, isn't he?

But before you say, "Never", read this- http://www.oldminibikes.com/forum/b...3-briggs-5hp-lighting-coil-wires-hook-up.html

If you can find a military suplus 5hp briggs, good luck. It defeats the purpose, he wants to add a charging coil, not get a new engine.

Who said anything about a new engine? I said if he could find parts. And looky what we have here-

Pay attention to items "C" and "D" on the chart.

Great, now looky here-http://www.smallenginesuppliers.com/shop/html/pages/products/Briggs_Stratton_ignition_coil3745.html
Next?

Only fits 3 diffrents models, and ones a vangard. Is that external, or inside? You could mount it , but how? And does it require a magnet on the inside of the flywheel to work?

Cheap, cut a hole in the shroud to fit it, it may take some tweaking but it will work.

 

[Doc Sprocket]

We don't even know what model he has, or is/is not capable of- So why don't we just suggest it's possible, because it is- and let the OP figure out if he's going to go to all that trouble or just take another route. No?

EDIT- for the OP's research benefit- a model application chart- http://www.smallenginesuppliers.com/html/engine-specs/briggs/alternator/Where_Used_494254.pdf Looks like a lot more than 3.

Would we care to re-think this?

Thats man, you did all my research! I watched kipkay on youtube instead, and now I know where to buy, thanks!

After running through Google Translator: (and spell check)

Thanks, man! I just learned something new- I could have spent five minutes researching on the internet before swearing up and down that something didn't exist, instead of watching stupid YouTube videos and looking like a fool! Thanks!

Really- can you not just say, "I guess I jumped the gun on that one", and leave it at that? Do you have to act like a schmuck, too?

Pretty much.

 

[landuse]

This has turned into quite an entertaining thread...!!!

 

[Doc Sprocket]

Sorry to disappoint you Landuse, I'm not going any further with it. The OP can decide what he's willing to do with the provided information.

 

[Franklin1283]

Thanks!

Thats alot of info, so thanks guys! I may just wait till I change the engine, and just find one that has one built in. If it take away from the power, I really dont want to do it at this time.

THANKS AGAIN!!

I'll prob be posting more dumb questions soon!
