Nice link thanks for that. I got quoted £74.00 for the replacement listed for my bike or £94.00 for a 2002 bikeunit but the guy said he could not see any difference in the two units and that he would have to check with Ducati. The Electrex one is the same price at about £75.00 but is it better? I have just removed mine and the two connecters are heat damaged, I will have to take a look at the alternator end at the weekend. Thanks for all the advise I may be back for more.
