Hello,

I have a Dyna 2006 and plan to replace the stator (38 amp) with a 2007 type stator (40 or 50 amp) to make it fit with the rotor to the SE Compensator.

Do I have to replace the regulator?

I have heard/read that the Dynas 2006 and 2007 have the same regulator and that the Dyna 2007 stator is 40 amp. (But I have not got it confirmed.) If so, I should be able to use a 40 amp stator with my stock regulator. Is this correct?

Anybody here who has made this trip?

Thank you so much

 

The regulator is the same part number for the 06 and 07.


Rotor is also except last two numbers. Interestingly the rotor is $406 for 06 and $247 for the 07.

I really am not saying rotor is going to work. Harley is implying regulator will.

 

Thanks for your answer. Good to know that the 06 and 07 have the same regulator.

All advertisements for the SE compensator (which includes a rotor) say you need a ”07 style stator” if you want to put it on your Dyna 2006. From that I assume it will mechanically fit on my bike (which is, by the way, very similar to the 07 Dyna). I have no reason to believe the 07 stator will not fit.

And now that you helped me to confirm that the regulators are the same, (which I remember a seller also has mentioned), I do not think I need to replace the regulator.

Sounds good. What I wonder about though, is that Cycle Electric sell a 07 stator with 50 amp and not 40 amp, (which I think the 07 stock has). So will the stock regulator handle 50 amp? To be on the safe side I will look for a 40 amp stator, I think.

Thanks a lot Sir for your answer, and for sharing the link. This was very valuable to me.

This is from harley-davidson.com:
"Fits '06-'11 Dyna®, '07-'11 Softail® (except FXCW and FXCWC), '07-'10 Touring and '07-'09 CVO™ (except '09 FXSTSSE) models. Does not fit Trike. Requires separate purchase of Installation Adhesive Kit P/N 11100088. Kit includes Rotor Assembly P/N 30041-08. Installation on ’06 Dyna® models require separate purchase of ’07-style stator."

 

Be sure you carefully measure off that inner primary cover to the face of chain sprockets to make sure all this change doesn't misalign anything.

 

all things being equal, yep the regulator will work, based off the load and hd says the stock load is basically the same.
the capacity is based off the semiconductor being used as the output or power handling control. the rest of the circuits just tells the output when to turn on/off. the regulator has crowbar circuits that fix within a range the output voltage/amp.
if you have a 50 amp and the machine only uses 40, no issues but if you use 50 then the regulator is running wot. ideally you should have a 20% headroom to make sure the battery gets charged. the machine runs off the regulator and the battery making up any short fall. pushing a regulator creates heat and electronics do not like heat. also, hd seems to push the limits being just so, enough to get the job done and nothing more hence saves $$$$$.
also the type of regulator matters but hd long got away from the single output to a flip-flop output which handles more load with less heat since each semiconductor only carries half the load.
the newer regulators (which hd does not use) are of the SMPS type where current is controlled by time which are highly accurate and way less heat but cost more. nothing new since scr has been around a long time.

 

From the other way round there is load created by all the parts on the bike the regulator has to be man enough to be able to supply the current requirements of that load. Similarly the stator has to be man enough to supply the current being drawn by the regulator. So it isn't whether the regulator can handle the stator it is whether the stator can supply enough current.

 

For those that have big speakers and 100,000 watt amps. And essential for that heatpump suit..

 

Thanks, now I understand.

 

This from another thread I was in awhile back.
It would take more time to research this to see if it apply s to your Dana.

My point is the rotors make a difference not stators.

"According to Ronnie's on a 03 RK the stator for a 38 amp and 45 amp (45 0n a police bike) are the same 29987 -02a.
The rotors are different # 38amp= 29981-95 , 45 amp= 29999-97b
The regulators have the same # listed for the 38 amp RK and the 45 amp Road King Police."

Good Luck WP

 

rotors are magnets for generating magnetic field for producing electrical current in a conductor. can rotors make a diff, hummmm, why sure such as stronger magnets and more magnets and etc.
BUT
a pmg is fixed so the stator is the defining component. insulation type, wire type and gauge and turns ratio are its concerns and it determines the output capacity.
a pmg is a sweet spot power generating devise with means low rpm = less output and too high rpm = less output, hence the unit is designed for the typical rpm the engine is designed around.
