I have an 08' HM1100S (Hypermotard) that is not charging properly. Before replacing any parts I was charging at 13.4V I replaced the stator with an aftermarket one but that did not change the charging voltage (still at 13.4V) I replaced the rectifier or voltage regulator and now I am at 13.9-14.0V If I check the output right at the rectifier I get 14.3V I have checked the ground and I do not suspect the battery to be the problem, initially I was thinking I have a weak or dieing cell in the battery. I tried a new battery (which was temporary because it was going into a friends bike). This was the first thing I tried before replacing any other parts and there was no change in voltage. I do work on bikes for friends occasionally so I am a pretty competent mechanic but this problem has me stumped. Anyone ever run into / come across this? Thanks in advance. FYI the bike was purchased new, still has original Yuasa battery, bike is pretty much bone stock aside of a speedo-healer, FatDuc O2 Eliminator and an aftermarket airbox lid."
