External Alternator

Thinking crazy thoughts...it was mentioned that someone had pulled it off and I was wondering if anyone else remembered seeing it done and maybe who did it? Searching the forum for "alternator" recovers too many hits and searching "external alternator" just doesn't get enough.

If anyone remembers anything about it I would appreciate the info...especially if you can remember how it was driven.
 
Google honda goldwing alternators, goldwing owners put auto alternators mounted externally on their rides for extra amps to run accssessories.
 
Not quite the same because they have a nifty belt system handy to run things like alternators and superchargers :)
 
Sorry thought it would help, but if you want to run an external alternator you will have to cut a hole in the cover, extend the shaft to connect it to an alternator and finally seal the hole with some type seal similiar to the ones used to seal a hole in a firewall of a car when running wires through it.

This may not help a lot but it's my humble 2 cents.
 
Thanks for the links. However, the GL has the advantage of having a dry shaft to attach a pully to. I can't really think of a way to do it for the GS without having oil leak issues.

Ultimately I thought it was a good idea because of the output but it's likely just not going to work. GL/CX owners have to sort stuff like that out, too, because they have to pull their engines to change their stators. All we have to do is pull a cover.

Anyone know what the amp/watt rating for the factory GS stators is?
 
Where there is a will there is a way. With all the bright people on this forum :-k I could see somebody coming up with something.:pray:
 
I thought about driving off the chain or countersprocket but didn't know if that saw the RPM needed to operate an alternator. Opinions?

The RPM at speed isn't an issue as you could always scale it with different pully ratios to get it right. The main problem is that in traffic, at low speeds, you'd be running off the battery.
 
A new cover wouldn't be an issue...the current stator covers could be shaved and a plate made to bolt over them.

running off the battery I could tolerate for the most part, I just don't like the idea of dealing with traffic. I have to do that pretty regularly. I think it would stress the battery quite a bit. But I do believe that an alternator from an FC RX-7 at least would fit in that giant gap the counter sprocket is recessed in. There wouldn't be any "stepping" though...I don't believe there's enough room there for an alternator AND a transmission system.

you can always change the gear ratio on your contemplated drive system to suit the rpm's need for the alternator.

so, what kind of wattage needs are you looking for?

What I really want is 300w, more would be better. My list goes as such:

35w HID low beam, on all the time
65w high beam
15w to tail
25w to brake
15w to turn (X2)

Thats my minimum requirements. But there's another 100w of accessories I would like to be able to run sometimes.
 
so your 300watt is requiring 23amps of use at say 13.5volts

23amps of draw isnt all that much
especially seeing as you wont be drawing 23 amps at ALL times

but i dont know what the stock output is either
 
have you given some thought to driving an external alternator from the right side of the engine. not the stator side.
then you won't have to worry about sealing systems for the crankcase.
make a spacer to replace the signal gen cover thick enough so you can run an internal pulley and run the belt through a slot in the adaptor. drive it off the large nut with a bearing on the outer (extreme rh side) to support the shaft and pulley load mounted in this "adaptor".

then choose/make a pulley to fit on a small/compact alternator.
 
I'm thinking you're probably in the 270-280 watt range already. In '83 they went to 310 watt stators on the 750. An RM stator would probably put you over 300. RM claims they put out as much as 20% more power than OEM.
