The upgrade fix >> no more charging/regulator/rectifier problems

From a Aprilia Caponord page Charging System | Moto-Abruzzo :

>>In fact, when out and about on all types of road from forest trail to motorway, the FH012AA operated at a consistent 42-43°C.<<



Two more quotes (forgot links, sorry!):

>>Be aware that such an upgrade will NOT provide more power for electrical accessories since the available power is limited by the output of the generator!!!<<

Pretty obvious when you think about it, but anyway.....



Even factorys seems to accept this as an uppgrade:

>>It looks like Triumph finally arrived late to the party, but the news is excellent - they are now supplying as Triumph OEM kit, FH012 R/R units as the latest warranty replacement on the Street Triples.<<

And a BIG THANK YOU f sharing this info w us, droplock!
 
crozzer-
greenmonster-
I'm not sure why you see this as disturbing, if Ducati are now using MOSFETs it's probably a good thing. My original post of this article was as a suggested remedy for older Ducatis like mine which suffer from meltdown primarily due to inappropriately rated wire gauge and poor connectors exacerbated by insufficient air flow to help dissipate heat.

It may well be that Ducati have been using MOSFET units for some time now, I don't know. I don't even think that there were necessarily models post 1999 using SCR units which had a propensity for meltdown.
I agree.
And I don`t mean to degrade your research, most grateful.
 
I talked to my dealer today.
Not a bad idea, is like checking tha manual sometimes..... :)

They nowadays sells 2 Shindengen units:
1 w 3 yellow wires & 1 w 2.
If I got it right on the 2 wire one:
Shindengen no SH579B
Duc sp part no 5404111C
130 Eu f that, 115 f 3wire.
2wire came in 2 versions: SS/M & 916/748, wiring differ.
No possibility f warning light on both IIIRC.
 
Mailed my father, old car electrics mech, this thread.
This mod should work.

3 things he said:
1. This construction shuts charging down when all is getting the juice they need.
= no heat & magneto field down- little bit more power (less restricting crank rotation).
2. 2 leads mean more harmonic distortion than 3, unsure what it could disturb.
3. He asked why
http://www.shindengen.com/resources/content/1/1/1/1/documents/FH012 Data.pdf
had the fuse on + to battery instead of the loaded stuff?
I dunno, had no idea these reg/recs where so complicated.
Anyone?
 
From st2lemans:

>>If thew device if rated at 50A 3p, then each leg is averaging 17A.<<

>>When used to regulate 1p, only two legs are used, so it can nominally handle 34A rather than 50A.<<


From http://www.ducati-upnorth.com/tech/chargingfailure.php :

>>It's important to note here that, given the obvious need to charge the battery, the stator wires will have to pass 29 amps (350 watts/12 volts) continuously<<

So,
if 29A is the max capacity current that the Duc 1phase alternator can produce,
how many Ampere do you get when you only use 2 pins in the Shindengen FH 012?

I may be slow when it comes to electrics but I just wanna know & b sure.
 
Great, thx.

If you use a smaller Shindengen FH 3phase, like a 30 or 40A one, you also get 29A when using only pins?
Or can a 30A only produce 10A per pin?

Just to b even surer....


>>Of course, 1p has much more ripple than 3p, so the peak currents will be higher and may stress the RR more.<<

Is that one of the reasons manufacturers went from 1 to 3phase, less ripple?
