alternator from genny conversion kit

[cajun1957a]

Im still considering the alternator conversion kit because of the genny chatter. Who has the best price around? Im in Ontario Canada so I have to take that into account. I dont see any used anywhere even on ebay so i guess im looking at big bucks, but none the less i think I may go for it if I can find the cheapest around.

I have seen them on the 'Bay for $200-250.. but not very often. I haven't heard good or bad about them except that they are spendy.. I went with a Cycle Elctric Generator and it is killer.. I take it the one you want is the one that lists for $420 and comes in black or chrome?

Here is what I would love to see for Sportsters.. what Alton has done is created a real Alternator for bikes.. this really charges the battery better and lets you run modern lighting. The first time I saw this was just a few yrs ago and made for Vincents.. the ones that fit on the end of the Generator just don't seem to be like the Alton which cost mucho bucks..

try Ray Dugauy in New Brunswick <saddlebagrail@yahoo.ca>, He converts car alternators to work in ironheads. I got one from him last year. Has regulator built in. looks like:

Havn't run mine yet as still building engine. He stands behind them though, says he and all his buddies run them. and no problem in rain.

[IronMick]

My local indie here has them in a standard catalog - as i recall the price is around $400, maybe less - i can check if you want. Any local shops down your way with the usual catalog suppliers?

My IH had an alternator conversion when I bought it, but it wouldn't charge the battery. Turns out, the cheap foreign made regulator was the problem. The alternator itself was still good. If you go with the alternator conversion, you may want to consider an American made regulator. They cost twice as much to start with, but only if the foreign made one does cr*p out on you.

[steve0suprem0]

sorry to resurrect a (fairly) dead post, but mick, i'd certainly appreciate that info if you wouldn't mind. i havent checked shops in my area since i plan on doing the work myself (plus i've just moved here and am waiting on my bike). i found this one which seems pretty reasonable, as far as these things go:

http://www.debrix.com/Generator-Alternator-Conversion-1965-1983-Harley-X-p/32-7528-vt.htm

also @85mm, would the brand new regulator i put on when i thought i had a good genny work or are they different? i'm assuming they're different. also, when you talk about weak unsatisfactory foreign vs robust verile american regulators, where should i start looking for one of those?

[85mm]

I found J&P will identify American made components. You don't have to buy from them, just use them to separate cheap stuff from American. By the way, American made stuff can be defective too. But I think you have a better chance buying American and you have a better chance of getting it replaced if it is defective. Life is a crapshoot.

so does a regulator for a genny work on an alternator?

I believe the answer to this is "No".

I totally agree! What model(s) regulator do you recommend as a replacement? Do you know how many amps this V-Twin conversion kit puts out?

The alternator comes with a H1686 regulator rectifier rated for 22 amps. Acell puts out a USA made replacement, p/n 201118B.

[asasial]

i think it's cool but i like being different. i'll probably get one when/if my alternator goes out.

Awesome, thanks! sounds like any Big Twin from 1981-1988 :banana I'll call Accel to see if the two outer wires are polarity conscious or do you know if I can get the Big Twin stator to reg. plug and wire it onto the alternator for a far superior connection than those crappy bullet connectors provided? My concerns now would be wiring up the Accel #201118 Regulator to the V-Twin Alternator. The regulator it came with didn't matter what wire goes where.
Thanks,

Right now, I'm having problems with my newly purchased #32-7528 alternator conversion kit. I suspect the regulator to be bad. Both Dealer and Manufacturer are giving me problems with a simple exchange. To make matters worse, I can't even get technical information without a "dealer's account number" :censor Never experienced this kind of customer service before. :censor Anyhow, if I could do it all over again, I would gladly get a kit from Ray. He's easy to get ahold of and talk to. Never went with Ray cause he didn't have any in stock and won't produce any till December or early part of next year.

[asasial]

i've been lucky... i did a no no and bought mine used with unknown age or miles on it. but it's been fine so far. but i found one of Rays on ebay after i bought mine and wished i had seen that first. i like the mechanical looking aspect of it.

That alternator looks fantastic. Hot Rodding at it's finest.

[boogieman]

hey thanks everybody i really appreciate the info im really feelin that alternater from new brunswick . but i still aint seen the one i seen in the mag acouple yrs ago. all ino is ive had this bike for 23 yrs and it hasnt charged all summer long any of them years.im in the prosses of choppin it now and i wonna keep the chargin system as simple as possible. im sick of changin generators and voltage regulators

[asasial]

the standard alt conversions seem to work well. i'm running one no problems so far but you have to run a regulator with them but hook up is simple 2 wires into the regulator one out to the battery

I love the mechanical look of the Ray alternator. Course, I've always been about function over form. Hope I said that right. I will check him out when I have problems. I'll probably be sorry I said that.

[Joey-D]

I like the look of the ray alternator also but how will it stand up if I get caught in the rain?

Looks alot like the one under the hood of a car and they work fine when it rains. :dunno

[Joey-D]

But there is no hood over them on the bike. They are not exposed to water in a car.

Apparently that is a 40 amp alternator from a Kubota tractor. If comes with 2 mounting ears on it like in attached picture. My guess is they are cut off and the case it powder coated black. Now I just need that machined mounting plate. The price of the alternator off google shopping is $104.95. Also here is a link to wiring these alternator....

should be easy enough my boy at my local machine shop will have no trouble with mounting plate, I'm curious about the shaft and how the gear fits ???

[Joey-D]

My guess it is machined down and the to accept a little bit of the gear and then a stud holds the rest on.

[billeuze]

The alternator from Ray comes without the generator gear. I had to slip my own gear on the shaft. Ray had already made the shaft the right length and machined splines in the shaft so the genny gear slips right on with a bit of heat and some tapping (press fit). There's no stud. He must have welded a shaft extension and then machined.

Thanks for the links to the wiring. Hmm, on mine, one of the wires was supposedly for connection to a tach on the original vehicle, Ray says don't use it. one of the other 2 wires is for switched power (to excite the field windings), the other I forget. I'll check when I get home on the weekend.

[einheit 13]

Toyota trucks use the same style alternator too. I saw a pic an ironhead running an alternator off a belt/pulley that was connected to a jackshaft set up at the genny hole...use to do this to pr e unit triumphs when the genny went bad...

[Joey-D]

Johnny Bravo, if you get one of those plates machined, let me know. I will pay you to get one made for me too. Here is a break down of the measurements.
5/8" Thick Base
7/16" Thick Collar

http://i272.photobucket.com/albums/jj179/JoeyDi84/Untitled-2.png

[Joey-D]

So I just had an epiphany as I was taking measurements off my existing generator. Why not modify the base of my old generator to accept the alternator? Then the only thing that will need to be machined is the shaft. The shaft length that it comes out of the alternator should be fine as I can cut down the "mount's" thickness. So really then I just need to attach the gear. I could just weld that on. Here are the pictures I started to take before I realized I could just use the base.

I ran to orielly auto parts and even under my account, it was $287.18 plus $100 core for the alternator. So I will be buying it off the internet for $104.xx. Here is a cross reference sheet. Any of these should be the same 40 amp alternator.

iI talked to him a little while ago, I've got to go back tomorrow but he said should be easy, I'll take some photos with me and get back to u, around 100 bucks probably

[Joey-D]

I think I am going to try and use my base first. Once I get the alternator in hand, ill decide if I can use my generator base or not.

[jonnybravo]

ok man let me know,

[Joey-D]

Is it safe to run a 40 amp alternator? I have a small battery that is the same kind that you would find in a v-rod. Will it over charge the battery and cause damage?

You can put a 100amp alternator on there if you wanted......Thats why you have to run a voltage regulator...it cuts the charging power to the battery when the battery is full....:doh

subscribing.. inquiring minds wana know:tour

[jonnybravo]

I'm doin it. it'll be in a couple of weeks but I'm going to the machine shop again tomorrow, i might get a lot of 10 mounting brackets made, I'll let u know

[Joey-D]

Im gonna order my alternator tomorrow. Had to deposit the cash first. Then I am going to see if I can modify my generator base to work. I will keep everybody informed. Just FYI, the frame and tins are at paint right now, so it will be a while before I can actually test everything out. But getting it mocked up is really most important thing at this point. I might also pull some alternators at the part store to see if there is a cheaper alternative. Really it just needs to be a low amp alternator that is small in size and have a built in regulator, which all direct wire car alternators should.

[jonnybravo]

I am interested in seeing the shaft, if u could post a picture so i can get an idea as to what the untouched original looks like that would be great
thanx

[Joey-D]

This one caught my eye, I emailed the seller to try and get the diameter of the case. It just need to be around 3.73 or smaller. It has a internal fan and internal regulator and is also 40 amps.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270691912540

[Joey-D]

I ordered my alternator, $77.95 including shipping. I chose a different one. Has an internal regulator and internal fan and is also 40 amp. No one could give me measurements of the case, but knowing the bottom hole was 10 MM, I was able to measure off that on the computer. The case should be 95 mm diameter, or roughly 3.74 inches.

heard anything yet Joey ????

[Joey-D]

I have recieved it but way to busy to install it the size is good. I'll keep you updated

[jonnybravo]

is the shaft gonna require mods for the gear to work ????

[Joey-D]

Got a second to play with it today. I have made the mount yet, I am thinking I am going to mount the alternator directly to the lower unit. I will probably have to lightly modify the alternator to mount it. As far as the gear mounting, I plan on drilling out the gear and tapping it to M14x1.5 and just screwing it on the alternator shaft. It should be spinning the direction to tighten the "gear nut". I just ordered the tap a minute ago. I will keep you updated, but with a pregnant wife on bedrest and a car dealership to run, it might be a while before I can play with it again.

[jonnybravo]

cool I'm going a little different route, I talked to my boy and he said no problem on the machining the adapter plate, so I'm going that route, probably gonna do a prototype soon I 'll let u know

[since79]

I love it...

[jonnybravo]

still looking for a closeup of the shaft ????

[bustert]

i'm with iron mick!! functionality supercedes looks. it could be dressed up a little nicer but cooling would be an issue since the original setup relies on an external fan. water&dirt time will tell.

[gypsybiker45]

If it were me, I would use a GM alternator and avoid the ND.irregardless of what the guy says about being ok in the rain,that series alternator has a tendency to rot away near the terminal screws. its just a piece of tin covering the workings.Ive seen it countless times on Chrysler cars. The GM /Delphi unit has an internal regulator which eliminates the Tympanium style rectifier/regulator that I simply hate.IMHO that style regulator is best used on garden tractors and snowmobiles and Nortons and Triumphs whos zenor diode has failed,crap unit.

[carbineken]

I know this is a pretty old thread but has there been any progress.

[Joey-D]

I sold my bike as a project about a year and a half ago. The guy was using it to hang in the back of his bar so I doubt it was ever finished.
