fernando Posted October 31, 2005 Share Posted October 31, 2005 i located this company in the net, EUROMOTOELECTRICS they sell upgraded charging systems for guzzis. but from what i read ,it will only retrofit pre 1999 bikes take a look at it . i think it will not work in newer bikes .but maybe some of you may find this helpful. the name was given to me by a guzzi rider i met today on the road .

Murray Posted October 31, 2005 Share Posted October 31, 2005 Odd the charging system on the pre 99 bikes is the same as the post 99 bikes to the best of my knowledge anyway. Its only ever changed for the 1100breva/griso. Athough having said that I have never actually felt the need to up grade the charging system on my bike.

I suppose if you switch out the regulator it could work if the parts fit. Link to comment Share on other sites More sharing options...
jrt Posted October 31, 2005 Share Posted October 31, 2005 And rotor weighs 8% less than the bosch rotor!! Actually, I may have to get something like this for the G5. Thanks for spending my money Fernando! Link to comment Share on other sites More sharing options...
Paul Minnaert Posted October 31, 2005 Share Posted October 31, 2005 I'm not good in the old stuff, Pete is, but what I've seen, the crank dimensions are different depending on alternator make used. From what I've seen in the picures it's the same as on daytona/v11 used, same Ducati unit. Link to comment Share on other sites More sharing options...
callison Posted November 1, 2005 Share Posted November 1, 2005 At some point, Guzzi switched to a tapered nose on the crankshaft and that's what all of the Ducati Electrica systems have. I think, but am not certain, that anything prior to that does not have the tapered crankshaft nose so the upgraded kit intended for the older Guzzis and BMW's probably will not fit on the newer Guzzis. Too bad. Link to comment Share on other sites More sharing options...
dlaing Posted November 1, 2005 Share Posted November 1, 2005 FWIW while the maximum output (32A vs. 27.5A) of this alternator is higher than our OEM, at 2000RPM the output is the same, 20A. Link to comment Share on other sites More sharing options...
docc Posted November 1, 2005 Share Posted November 1, 2005 If your Sport is happy lumping around at 2000rpm you must have a PCIII AND Tuneboy. Link to comment Share on other sites More sharing options...
dlaing Posted November 1, 2005 Share Posted November 1, 2005 Heh! It ain't that good with the PCIII and Tuneboy. It lumps around pretty well at 2500rpms, though! But it lumped better at 2500rpms with the Quat-D ex-box. But the point is that at idle, the two alternators are going to have pretty similar outputs, which is when most of the lack of charging occurs. I suspect the OEM charging system is good enough for heated grips, and a heated vest as long as we are doing long highway miles. (Doing short city trips or add heated boots and panties and you may get a dead battery) Link to comment Share on other sites More sharing options...
docc Posted November 2, 2005 Share Posted November 2, 2005 Now I see the 27.5a ( 350 w ) output is at 10,000 rpm! Like I thought i cruised with the revs up! Link to comment Share on other sites More sharing options...

docc Posted November 4, 2005 Share Posted November 4, 2005 From the chart it appears the typical alterntor output, assuming cruising at around 4000 rpm, is more like 315-320 watts. So what do the running systems require? I've figured just under 100 watts for all the lights except brake and turn signals which would bring the load up to 135w. ( I'm using a 77w hi-beam). The Gerbings rep told me that the FI takes 50-60w. This I'm having trouble figuring. What does the ECU draw? Coils and injectors? Fuel pump? If the 60w figure is adequate then the bike will run all its systems (except horns, brake light , turnsignals) on 200watts. Adding 99w of jacket and gloves takes the draw to 93% of capacity at 4000 rpm. Seems safe enough? Add to this heated grips, a hotter headlamp or drop below 3300 rpm and it's you and your battery.

jrt Posted November 4, 2005 Share Posted November 4, 2005 Fuel pump? This articleindicates that the fuel pump draws up to 6 A, so that's 72 Watts. Sheesh. I doubt the ECU draws even one amp, but I'd let Cliff (or Dlaing or Moto) answer that one. Coils? No idea... Link to comment Share on other sites More sharing options...
