Alternator Rotor
I have a 22 Amp Cycle Electric Stator and Regulator / Rectifier. I have an original 1984 FXEF Rotor. Will this Rotor work with the 22 Amp stuff? Will it still be 22 Amp? For the record these are spare parts. I have a complete cycle Electric 22 Amp system on my 1984 FXEF. I posted here instead of electrical as it is Shovelhead stuff.

Mine is a very late 1984, Wet Clutch from the factory, 1HD1BBK2. To be honest, I should have tried to Delete this post. I am pretty sure that all FXE Shovels were 22 Amp from day one. I always think I upgraded to 32 Amp! I was going to at one time when the MOCO was selling those 32 Amp EVO upgrade charging systems for peanuts. They never had one in stock when I needed one.

I believe the late Shovel system was the same as the early Evo system... actually pretty sure.

My 1976 FXE was two pin but opposite my 1984. One has the pins inside the engine case and one has the pins on the plug from the regulator / rectifier. I do not know the real early FXE charging system configurations but believe all FX were 16 Amp and FXE were 22 Amp. But my memory could be bad on that. Maybe the 22 Amp was an upgrade afterall? I know FX and FXE were different ratings, but I may just be confusing battery power with charging systems. Getting old isn't easy, but it sure beats the alternative! That amperage info should be somewhere??? One would think? All would be cone case alternator models, all post Generator.

Let me re state ...
FX/FXE had 3 different charging systems... The earliest 4-pin, then the mid years system...and then a later System... Maybe starting 19??? ... 82?? 1) 4-pin, 2) 2 Inny- pins, 3) 2 outy-pins!!!
I believe the late Shovel system was the same as the early Evo system... actually pretty sure.
The 3 systems brought progressively more Amperage ...
I do Not recall the FX having a different system from the FXE... Nor the FLH for that matter...all 3 had their own different battery however!!! After about 1973 or so

I know exactly what you are saying as far as the charging systems not only getting stronger, but also much more reliable. I remember back in the 1970's and 1980's motorcycle batteries barely lasted a year, and this was down south. The biggest problem that I remember was they were overcharging all the time and cooking the fluid out. Another problem was burnt pins on the regulator / rectifier to stator connection or the plug coming out during a ride. You didn't have enough battery to start an electric start bike because you had been running on battery power the last 60 miles; Point ignitions didn't use near the juice as electronic. If you had electronic you would know there was a problem in short order.
The AGM batteries just amazed me how long they lasted when they first appeared. The downside to AGM batteries, especially the cheap ones is they fail without warning. They don't start showing signs of weakness they just quit running down the road; two or three engine misses and blinking lights, then poof...Nothing.
For the record I will use a Cycle Electric 22 Amp Charging System and a O.E.M. Harley Davidson AGM Battery in a Shovelhead over anything else out there.

As Racepres stated all rotors are not the same
For FX models
29965-70 (70-75 19 amp w/ 4 pin connector)
29965-75 (76-80 18 amp w/ 2 pin connector)
29965-81A (80-84 22 amp with 2 pin connector)
For FLH models
29965-70 (70-75 19 amp w/ 4 pin connector)
29965-75 (76-80 18 amp w/ 2 pin connector)
29957-81B (81-84 22 amp w/ 2 pin connector)
Still have the original system on my 78-1/2 FXE. On my 84 FLH I updated to a 32 amp Cycle Electric system but kept the original (it was working just fine; just liked the idea of a little better & more pwerful system)

panz are you talking rotors or stators? The stator has pins, or are you combining the two features of each era? I guess my original question should have been does the Rotor have to match the Stator? I know Stators come in various amperages but didn't know if there was any difference in the Rotors as far as making juice?
My original 1984 charging system crapped out too many years ago to remember the specifics. I know I had burnt pins and attached new plugs but can't remember why I ultimately swapped it out.
