Topic: 45 Amp Charging System? (Read 14659 times)

I've got a question for one of you most enlightened poobahs, is the high output 45 amp stator (29999-97B) OEM on the 05 SEEG?
Last night while riding in 29 degrees, I had heated gloves, heated jacket, heated grips, heated seat, motolites, spots, and HW amp all cranked up and began to wonder if I might need some additional charging capability.

At 45 amps you should have a nominal 540 watts of available capacity to run all your goodies, roughly.

You should be able to find out how many watts each device requires...

45 generator amps x 12 system volts = 540 watts

I have an aquaintance that has a penchance for goodies on his road glide and had a 3 phase alternator installed on his bike for air compressors, lights, heaters and I think an ice maker too...

No Mark, ours do not have the 45A stator. I believe this has been asked before and 2lane has the extras you are talking about with no problems. Bob (I've got everything you mentioned less the heated clothes)..

Bob's spot on MJ. The SEEG's are 38 amp. As they'd been for several years before. If the primary is ever off you could put a 45 amp upgrade on. Easy enough chore if you're in there. Even though I've thought about it several times I've not done it though.

As Bob mentioned I've ridden all day with the seat on, heated jacket liner and gloves and used the radio with the HW amplifier. When the stock headlghts were installed running the spots at the same time seemed to max out the system. I'd notice a little needle dance. Installing the HID lights regained a small margin of error though.

Some had questioned before whether "stock" 05 bikes were 38 amp system and CVO bikes got better. They did not. Easy enough to check in the parts manual. Or; here's the SEEG.

More great info..........

Cool..... Being a new SE owner, this site has been an interesting read.

Thanks,

According to my '07 Service Manual, all of the FLH/FLT's have a 50 Amp Alternator on them. When did it change from the 38 Amp?

Hoist!

Twolanerider · « **Reply #6 on:** December 03, 2008, 01:20:28 PM »

Just thought of something else MJ. If you're considing a charging system upgrade let me know. There's a company here in Joplin that is the OE manufacturer for a lot of the aftermarket. They make nice parts too. Can pick up a rotor and stator together for $150 if I remember right. Rotor by itself I think was about $80.

As many times as I've been in there for some reason don't know why I never popped the rotor off and changed it? Just hasn't been necessary. If/When it ever fails on either bike they'll get upgraded then.

Was thinking about exactly that as was writing a moment ago. And I don't remember whether the change happened with the 06s or 07s. For those of us with the 38 amp systems the up to 45 is easy should the need arise. And that's going to be plenty for 99.9% of us. After all, how many actually strongly push the limit on the 38 amp units...

Prolly changed with all the other stuff they changed down there on the '07 FLH/FHT's, that became HD's proprietary new design.

Hoist!

Thanks guys, I don't think I need to make any changes now, I'll just turn off the motolites, grips and/or spots if I notice the needle dance.

According to Harley's "never wrong" shop manual, the '05 FLHTCI, FLHTCUI, and the FLTRI were the only models to get the 45 amp rotor, all the rest of the Touring line got the 38 amp. The part about that that has always confused me is why the FLHTCSE, which is based on the FLHTC but has the injection like a CI, didn't get the 45 amp rotor.

Oh well, as Don stated it's an easy upgrade if anyone really needs the extra output. Just be careful installing the high output rotor, since the magnets are stronger and could get your fingers pinched (or worse) between the rim and the crankcase.

Jerry, that is exactly what everyone here in my office said. "Better be careful you don't lose a finger tip or 4 or more."

They certainly will pinch hard if you give them the chance. I cheat and use the little puller tool as a slow release. Got bit once and it won't happen again.

I talked to Cycle Electric and he said th 45 Amp Rotor is expensive. I think he said around $200.00.

I'm pretty sure the change to the 50 was in 06...my SEUC had that, if memory serves me.

If I remember correctly the Harley branded rotor packaged as an upgrade is MSRP at $265.00. Have seen some of the aftermarket selling a 45 amp rotor for between $180 and $220. The local shop that is an OE for some of the aftermarket has a guy that offers product somewhat directly. Knew he at least used to do some selling on eBay also. Just checked and he's still there. 45 amp rotor for $80. That's not nearly as painful.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=110293937639

Only difference immediately apparent is the Harley branded kit includes a (stupidly expensive when priced by itself) outer primary gasket. So that's 32 bucks to spend on top of the price of the rotor.

This thread shows the damage that can occur to a "loose" comp nut (addressed in a TSB)

http://www.cvoharley.com/smf/index.php?topic=34375.0;all

At the end it shows the "normal" "special tool" I used to install the rotor. As mentioned above - very strong magnets - you can and most likely will hurt yourself and probably damage the magnets if you don't use some type of installer.

I was just wondering if I could get some feedback on the Charging system topic:

1) Am i correct that my 04 FLHTCSE has the 38 AMP charging system?
2) Is it possible that my charging systems can be upgraded to the newer 50 amp system? Anyone done it?
3) Anyone have a parts list, if it is possible?

Thanks for any feedback the forum members can offer ..

Dave

1) yes
2) Yes, Porthole is doing it now.
3) All you need is to buy the 45Amp kit listed in the Harley accessory catolugue (part# 29999-97B). Plus a quart of primary oil and I would replace the compensating nut while you were in there.

porthole · « **Reply #19 on:** March 11, 2009, 07:03:57 PM »

Follow TwoLanes links and you may find the rotor (non HD) for under a hundred, or buy the HD for about 240. The HD kit comes with a primary gasket.

If you change the comp nut as Bob mentioned you should torque it per the TSB below.

In fact you should just do it the odds are against you not having the problem.

Has anyone changed out an old two phase system for the new 3 phase system ?
I haven`t heard of anyone loosing a stator with the 3 phase charger.

VRODDAVE · « **Reply #21 on:** March 13, 2009, 07:39:10 PM »

Thanks for the feedback guys ..

I have talked to somone on another board that claims to have installed the 2006 three phase system on his earlier model Ultra. He was not totally sure on the part number for the rotor, but he did say that the rotor he installed had 12 magnets on it. He felt that his charging system was rated greater than 45 amp.

74505-06 voltage reg. assembly
29987-06 stator assembly
29943-06 ROTOR ASSY, 3 PHASE (taken from 2006 parts list)
may need repair pigtail, part number unknown, to connect regulator to harness.

Can anyone here confirm if the part number ive listed for rotor is the 12 magnet

Are there ways of getting additional amp output through different compinations of componets?

VRODDAVE · « **Reply #22 on:** March 15, 2009, 11:17:07 AM »

So I have been out buying parts for this new 3 phase system .. Ive been told by parts counter that all nubers cross ref to the 50 amp alternator setup with an A or B for the stator ..

I ended up buying the 74622-06 regulator as it is the CHROME one .. I think I have the part number for the repair pigtail, 74115-06 , to splice ... but if anyone is able to confirm, as I have not located one yet, it woud be very helpful ...

Interesting, that the 29943-06 ROTOR ASSY is MUCH lighter than the original .. and in fact 1/8th inch shorter in height when they are lying face down on the bench side by side .. does this seem correct to you experts out there?

74505-06 voltage reg. assembly - 74622-06 chrome
29987-06 stator assembly
29943-06 ROTOR ASSY, 3 PHASE (taken from 2006 parts list)
74115-06

- repair pigtail

to connect regulator to harness.

Any help would be appreseated ...

Well, I completed the Install of the 50 amp alternator, using the above mentioned part numbers.

It works Great in my 04 ... moving on to the next project ...

Thanks for all the help, comments, feedback ...

oh, and sorry for hijacking the 45 amp thread ... I will try and do a better job of not doing that in the future ...

No need to apologize. A lot of the threads get "jacked"..

Glad your update worked out.
