i was talking to i think someone at af1 when i had to get a rick's stator for an aprilia and they were saying that the current aprilia genuine replacement alternator assemblies have "softer" magnets to reduce the output and help them live, which i thought was interesting. but i've not heard of that being an issue with the ducati. same part number was used into 1198, although it now ends in 2, not 1 so maybe there was some change. again, not that i've seen a lot of them fail in 749/999. only this one.
owner has bought up just getting a s/h 1x98 one and fitting that, but it's always the time factor and it's a commuter.
all the dead ones have had all phases with a short to earth, and a heavily burnt section somewhere. new reg (std sh579) went in when the first replacement was done. always has 14.1 - 14.2 when it's good, right up until the stator shits the nest.
the auto elec i call when i need advice says that a mosfet reg might help it because it doesn't take all the output load and dump the excess to heat like the sh579 does, it just takes the output it needs and clips the rest. but i don't get how that works. can you just set the phases to open circuit or the like and nothing happens? i thought that would hurt the alt, but is the output just a potential thing until a load is placed on it?
he also said the electrex world ones tend to be quite good in his exp, and being eastern european meant they were from a good source. remember when eastern european wasn't so good?
i could have the original rewound - it's been sitting on my office floor for a year or so, and i had meant to send it to jack to get rowan to do it for his stock, but never got around to it. maybe i'll do that.
