1000+ Watt Alternator - Feedback anyone?

[GJS]

Hi there,

While snooping around eBay for Valk parts I found this.

http://www.ebay.ca/itm/260656767085?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1680wt_489

Anyone got one of these?
I now have about 200+ LEDs, Fog Lights, Dual Headlights, Stereo and a heated vest. Everything is fine so far.
I am considering getting a full heated liner and pants for me and my gal, as well as looking into the "dayLong' heated seats for my 99IS. I'm  thinking the additional heated components will take me over the top of what the OEM alternator can handle. And I am also concerned that a MUCH Larger alternator might also have its own issues.

I have seen other posts referring to some bigger units affecting idling and low RPM charging.  I'm concerned this may unit be worse.

Thoughts?

Thanks

Glenn

Check the tech archives for a post by MarkT for his GW alternator install.

It will fit the motor, but be prepared to cut a notch out of the frame to get it in.  Those are for Goldwings, that do not have the clearance problem.

I've run a 90 amp Compufire alternator for maybe 10 years now.  No problems, but I did have to cut the frame to fit it.  Looks to me like that alternator is longer than stock, and you may have fit issues too, though I see they claim it's for  valk.  Doesn't look like it in the pic to me.  Probably not a problem if the housing isn't longer.  Where did the get the extra power - rewinding it?  So it fits in the same space?  I'm a believer in doubting the "something for nothing" theory.  I suspect there are space costs.  http://www.horseapple.com/Valkyrie/Tech_Tips/Compufire/compufire.html

Here is the link to the install from Mark T, involves cutting the frame.

I sent an email to the guy selling the altenator on ebay and asked:

"I understand that this altenator will fit a Valkyrie, but you have to cut the frame to get it in place.  Is that true?"

He promptly emailed back with this answer:

" No I think only the output position is not same if you want you can send me any picture from your old alternator and I will give you the right information,email me at altstarter@gmail.com ,Thanks"

Maybe he has a solution for a high output altenator that doesn't involve cutting the frame.  It wouldn't hurt to contact him  and discuss it.

Great job on the write-up

I'd hate to try and fit that in a Valkyrie frame.   That looks worse to fit than the GW version.

Your 105 LED's don't have much draw.  Your other stuff, you would have to figure out the draw, and add it all up.   Then go from there.

Thanks Mark. Great write-up!

I think I'll take FUDD's advice and drop him a line.
It does look long, doesn't it?  
Cheers,

I've fitted that alternator, it works without cutting the frame, you have to remove the output terminal completely and reattach after install, not easy but achievable, I've done it three times now.
Two things to watch for, when/if you get it check the housing alignment, mine was out 33 degrees, a pain when you discover this after getting it in that tight spot and have to take it out again to line up. Also the drive couple retaining nut on mine came loose after about 1500 miles again had to strip it out and loctite it on, worth doing as a precaution prior to install, use the strong loctite.
It works fine, I run with a volt meter and it shows charging at about a grand, no issues and the right money, even after paying import tax. Hope this helps.

Thanks Mick.

That is what I wanted to know.

The seller is useless. I have exchanged several emails with him. I think english is not his first language. All he wants is pictures and part numbers. (I sent him both the first time he asked)

I assured him the part number was correct and sent him a long note explaining what the problem might be if it is longer. He sent me another response asking for part numbers and pictures.

I asked him for a reference. He asked for part numbers and pictures.

Would you say your new alternator is the same size and weight as the OEM?
I'm curious how the extra energy is being created. More windings of a smaller gauge wire maybe?

Thanks Mick.

Best regards,

Glenn

With out rereading the whole post, I think someone mentioned this was for a GW. In a post around 1 year ago, they mentioned that the GW alt would work in the GL1500 Valk if the front housing was reclocked. Same alt, just the housing off by that 33 degrees that you mentioned. So they are interchangable back/fourth, after you realign it.

They are the same, just remove the 3 screws holding the case, and rotate it 1/3 turn. I do it on a regular basis. when removing the screws, hold the rear, and the center section, and rotate the front part of the housing.
