A friend has one of these 2007 in 1000 flavor not charging. I’ve looked on the internet and there seems to be more than one answer. Looks like more than the common Honda regulator/rectifier problem. Looks like big money has to be spent or not? Any ideas? Battery seems good with good connections. 12. 33 volts running or not. Rev it and battery reading 12.27. Nothing going in. All help greatly appreciated. Don’t want to be fitting parts and still have same problem. JJH
